Electricity Saving Tips For Homes And Offices

Evaluation and comparison of Superfan, a BEE 5 star rated fan and regular fans

By on January 23, 2017

Since we started Bijli Bachao, which was almost two years back, we have been experimenting with various appliances and measuring their electricity consumption. At our own home we measured electricity consumption of some of the appliances, replaced them with efficient options and estimated the impact post replacement. One of these is the ceiling fan. We were on regular fans about a year back, when we replaced them with BEE 5 star rated ceiling fans. And just 3 months back we replaced one of the BEE 5 star rated fan with a SuperFan, which is one of the latest Super Efficient Ceiling fan in the market. As we have used all types of fans we thought we should put up a little comparison between the three.

Evaluation of a SuperFan

We got this interesting fan 3 months back and we have been using it well since then. This fan has a Brushless DC electronic motor that is super-efficient. The fan does not need a regulator and works with a remote control (although they have a cheaper model that works without remote as well). In fact if you do not find the remote then it can also work by toggling the switch on switchboard the same number of times as the desired speed. There is a LED at the center of the fan that blinks and shows the fan speed when it is changed. Although a good feature, it can be disturbing at night while sleeping. Although this fan is a little different from other fans, the installation was quite easy and straightforward. We used our energy meter to measure the power consumption and it was as follows:

Speed

1

2

3

4

5

Wattage

3.8 watts

7.7 watts

13.8 watts

22.7 watts

35.8 watts

We did not have anything to measure the air delivery, but it felt as good as a regular fan. Also the air delivery quoted by the manufacturers is the same as that of a regular fan and we had no reasons not to believe them. The video below shows our evaluation of superfan:

Evaluation of a BEE 5 star rated fan

We have been using BEE 5 star rated fans for almost a year now. We have been quite happy with them, as they have certainly helped reducing our electricity bills. Although we have had some challenges with our electronic regulators (which we guess are not the right quality and thus do not alter the speed accurately). These fans are just like regular fans with a slightly efficient motor. As we mostly use our fans at speed of 5, these fans certainly helped us reduce our bills. The manufacturer quoted air delivery of the fan was just slightly less than the regular fan, and although a keen observation of the two fans would make you feel that the fan is a tad slow, but truly the fan did not feel bad on use.

As we had issues with our regulators, we had to measure two of our fans to get to right numbers for power consumption. Here are the numbers:

Speed

1

2

3

4

5

Wattage

13 watts

24 watts

30 watts

40 watts

55 watts

The one big surprise that we got was that the manufacturer rated the ceiling fan at 50 watts, but the measurement showed 55 watts at full speed. Below is the video of one of our observation:

Regular Ceiling Fans

We visited two of our friends’ houses to measure the consumption by their regular fans. One of them has 8-year-old fans that were truly in bad condition. The performance (air delivery) was poor and even the power consumption was high. Below are the measurements of the fans:

Speed

1

2

3

4

5

Wattage

13 watts

25 watts

37 watts

48 watts

92 watts

The other friend has fans that are 2-3 years old. And below are the measurements of his fans:

Speed

1

2

Wattage

14 watts

26 watts

39 watts

48 watts

76 watts

Below is the video of one of our observation:

Economics of Ceiling Fans

Below is an infographic that we published a few days back that can help you understand the economics of ceiling fans.

In case you are interested in doing calculations based on the speed at which you use the fans, then you can use the formula below:

Units consumed = (wattage x hours of usage)/1000

    about super fan the switch off on the remote does not completely switches off the fan,
    but rather it goes in standby mode while still consuming about 1.5W
    power in addition to that irritating led that keeps glowing,
    can we elaborate above matter

    • https://www.bijlibachao.com Abhishek Jain

      It would be about 0.5W and not 1.5W. And this happens with every appliance that operates on a remote control (even your TV, your AC, everything). The best option for any appliance with a remote is to switch it off from the plug point. Otherwise, some sensors have to keep on working to sense the instructions from a remote. And it will need some electricity.

      Also, LED does not glow all the time. It glows only when you change speed. In both superfan and gorilla.

    i have also confused in buying super fan or gorilla fan. can you help me?

  • Vineet

    Hi Abhishek,
    I have seen so many reviews that superfan is making humming noise. What is the reason for that? Compared to Gorilla fan by Atomberg whose poewer consumption is 28 watts, but super fan is 35 watts. Why superfan is not improving their design. The Atomberg is claiming no humming noise. So, it humming noise is a technological glitch. If I compare Superfan and Gorilla which have more air flow? I am planning to buy super-efficient fan for my new house but I am confused between Superfan and Gorilla.

    • https://www.bijlibachao.com Abhishek Jain

      Hi Vineet,

      I am not sure why people get humming noise. My own superfan does not make any humming noise. I think you will have to confirm this with the company. As far as air delivery is concerned, current as per the specs, Superfan has better air delivery.

    • Vineet

      Thanks for reply. I too don’t notice the humming noise while seeing the demo, but reviews are different. Can you comment why superfan is limited their design to 35W instead of improving it to 28W as provided by Gorilla fan and Orient Ecotech.

    • https://www.bijlibachao.com Abhishek Jain

      Hi Vineet,

      I am not sure why Superfan has not improved to 28 watts. What Gorilla and Orient Ecotech has shown is that the power consumption can be improved. But only the Superfan management can comment as to why they have not improved their fan.

    Sir
    What is the Air delivery range of Superfan ? Is it deliver air to the corners of room or just below the fan itself ?

  • Anant Bhatia

    Do you guys have any reviews of Superfan vs Atomberg Gorilla (which has even lower power consumption rating than Superfan)

    • https://www.bijlibachao.com Abhishek Jain

      We have tested all of them: Versa Drives, Atomberg and Orbit Greens. Here are some pros and cons of each

      1) Versa Drives:

      (some of the pros and cons mentioned are common for all)

      Pros: Great quality product with high efficiency and really good air delivery. You get the same amount of air as you would get with any good air delivery fan in the market. Extremely low power consumption (35 Watts). Backed by some really talented engineers from IIT Madras.

      Cons: Limited presence throughout the country. They have good market in South, but not much presence in North. Tech is relatively unknown to regular electricians, so difficult to get service (if it fails). Although they do replace the product if it is under warranty. But getting a replacement is a few days job and sometimes you cannot live without a fan. Finally using a remote control for a fan is a hassle (personally for me). Small remote control gets lost in the house and you keep finding it. Changing speed without a remote is a bit of a hassle. And remotes (for almost all appliances) do not last long unless you take really good care of them. They are expensive and are not as silent as what people expect at that cost. But then they are highly energy efficient and as noisy as regular fans. So compare them with regular fans and not the luxury fans.

      2) Atomberg: Most of the pros and cons above apply for Atomberg as well. But I think they have come up with a new design to make the fan work with a normal regulator (just confirm with them). This is a big relief. It is run by a team of engineers from IIT Bombay who are again quite talented. The product quality is good and power consumption is better (28W) than Superfan (versa drives). But Superfan has more design variations. Super fan also has more models. Atomberg is much newer as compared to Superfan, so their presence is lesser than Superfan. Ya and one more thing, there is a LED in the center of these fans that blinks when you change speed. Superfan blinks as many number of times as the speed, while with Atomberg it blinks only once. Remote control from Atomberg is of better quality than Superfan and is more feature rich.

      3) Orbit Greens: These guys are trying their best, but somehow they are the weakest amongst the group. The product quality is not as good as others. Firstly their air delivery is low and one may complain that that it does not give good air. Their remote control was not of great quality when we received it. It did not last 15 days. The overall experience was not really great as we could not change the fan speed after the remote got damaged. But yes, the electricity consumption was quite low.

      But most of the pros and cons are common.

  • shafi

    Present Price of Superfan 35 Watts is Rs. 3420/- and Havells 50 watts Rs. 2550/- Approx MRP. how does the table show a different Price? is there any Superfan brand at lower price?

    • https://www.bijlibachao.com Abhishek Jain

      When superfan started selling their fans, their price was low as they were giving less warranty (2 years). Now they give 5 years warranty and that is why they have increased the price. This table is a bit old. Thanks for pointing out, we will update it.

  • Parvez Khan

    I m using superfans from last 3 years… and i m fully satisfied with efficiency. …..

    • https://www.bijlibachao.com Abhishek Jain

      Thanks for the feedback.

  • S. Gupta

    I am also thinking if Superfan / Versa Drives is a fly by night shop. I placed an order on 7th March’16 on their website, next day got an email from Versa Drives that shipping details will be updated within 3 days. Today is 14th and no communication. No reply to email. Nobody answers their toll free #. Same about the chat service. I was lucky to use the chat once before ordering, and the experience wasn’t good, the chat was abruptly closed. When I said this was unprofessional. The chat guy came back to chat and said your issue has been notified to appropriate people. I went ahead with placing order after reading some product reviews. But now I wondering… If you read their 56 inch 5 years warranty tag. The warranty is about the motor and not even on the remote. What would happen if somehow the remote get lost or damaged. Will someone buy another fan for a remote. Also, the warranty is carry-in warranty, so if there is no authorized service centre, you’re done about warranty. And, there is no cancellation of orders. I am worried about my money now. Order ID: 7829

    • S. Gupta

      Surprisingly, the fan was delivered in few hours after posting here.

  • K. Gupta

    Superfan / Versa Drives is a complete fly by night operator. Deal with them at your own risk. Their business practices are unethical.
    Based on the review(s) above, I ordered 1 Superfan for trial, thinking that if successful, I would change all the fans in my house & in the company for whom I work. Amazon had the V1 model Superfan @ Rs. 3630/- delivered to me in Mumbai, on cash on delivery basis. When I contacted Superfan directly, they promised to send the V1 model to me inclusive of delivery @ Rs 3530/-, but I would have to deposit the cash in their account. I have the emails to prove this. I deposited the cash as per their email, even though their bank location was inconvenient. Superfan is now demanding additional 10% octroi, even though the email from Superfan stated it would be delivered at Rs 3530/-. The additional cost was hidden from me even though I had specifically asked about costs on the phone with them. Now I am required to pay an additional 10% or I lose the money already paid to Superfan. I am doubtful that such a company will return my funds. I am now not sure if the package to be delivered actually contains a BLDC fan or not. I may have to chalk up the loss of Rs. 3530/- to experience, & deal in future only with established fan companies.

    • K.Gupta

      UPDATE: –
      Subsequent to my post on this site, I received a communication from the company, & they agreed to supply the fan at the original contracted price.
      I am pleased to be able to say that I received the fan yesterday, largely due to the efforts of Ms. Susila from Versa Drives. Kudos to her! As it is the holiday season, I will not be able to get an electrician to install the fan for a few days. When installed, I hope to be able to review it for the benefit of the members of this site.

  • Bansal

    A 56″ Leading edge fan throws 26500CFM (778 CMM) almost three times the air any Indian fan throws, and uses just 110W. That gives it a rating of 7 CMM/Watt – more than any Indian fan at this speed. Whats more, its a split capacitor design.

  • om

    Fan power varies approximately with the cube of the target air speed

    P = c 2 V³+ c 3

    where P = fan power [W],
    c 2 = constant [W s 3 /m 3 ] and c 3 = constant [W].
    The two constants depend on the fan-person distance.
    If distance between fan & person is ignored, a generalized equation can be made : –

    P α V³

    Or, the power of the fan is
    directly proportional to the cube of the wind velocity.

    This has very interesting
    implications for manufacturers of “power saving” fans. If a fan produces 230
    CMM and uses 70 watts, the same fan at 210 CMM will use 53 watts.

    This is what most manufacturers of “power saving” fans do.
    They reduce the air throw of the fan to get lower energy usage figures.
    A reduction in air throw of 10 % equals a reduction in power usage of 25%.

    • Om

      In other words, you can achieve the same thing that a BEE 5* rated fan does, by just setting the regulator of your fan from 5 to 4.
      There are a very few manufacturers that actually make genuine energy saving fans, but all of them use BLDC technology.
      While it is theoretically possible to increase the efficiency of regular split capacitor fans, no Indian manufacturer actually does so AFAIK.

    On their website, Polar fans Winaire++ model claims a CMM of 295 for their 1400mm model, & 250 for the 1200mm model. Can these claims be trusted?

    • https://www.bijlibachao.com Abhishek Jain

      250 CMM is not very high considering that it is a 75 watt fan. And same goes for 18 Watts 1400 mm Sweep fan. Higher sweep can give more air delivery.

      Hi,

      Is it okay to use superfan x1 on modified sine wave inverter?

    • https://www.bijlibachao.com Abhishek Jain

      It should work well on modified sine wave inverter.

    • Kush

      Please note that the 1200mm Havells energy saving fans which you have recommended elsewhere on this site use 50W and deliver 215 CMM. The 1200mm polar winaire++ fans use 75W and deliver 250CMM .
      If the Winaire++ fan is set to use 50W with a regulator, it will deliver 218 CMM.
      If the figures given by Polar are accurate, then this fan is more efficient than the Havell fan, and can be set to deliver more air as well.

    • Kush

      My main interest is in the air delivery of the 1400 mm model. I have not been able to find a fan with greater air delivery than the 295 CMM that Polar Winaire++ claims. Superfan has just 230 CMM. This is a big difference, when you take into account that an increase in air delivery is proportional to the 4th power to the electricity consumed (for the same fan. Different fans have different constants).

    • Kush

      Sorry, air delivery is proportional to the cube of the power consumed.

  • Ajay Sharma

    I stay near Patna. This year I purchased some new fans for my house and store. I asked my local electrician and he bought fans for me. He brought Havells Turboforce wall and pedestal fans (18 inch) for my shop. I had also bought Havells turboforce exhaust fan (12 inch) for business purpose. For my home he bought Havells V2 (18 inch), Crompton Hi-flow, Bajaj midea and Modi pedestal fan (a local brand by Ansu engineering works, my electrician bought) (all 16 inch). We are extensively using all for 4-5 months.

    Now I have noticed some differences and i want to ask you some questions

    1) I found all industrial grade pedestal and wall fans in my shop has ball bearings, where as all domestic purpose pedestal, wall and table fans have sleeve bearings only my kitchen and bathroom Havells ventiliar DB has ball bearings. Why companies use sleeve bearings than balls in domestic grade products, does it improve efficiency or saves electricity?

    2) I found crompton runs cool same as Havells V2, Bajaj runs cool too. All have plastic cover over motors. The local company Modi pedestal fan motor (it is metal and has no plastic cover) reach 80-95 centrigrade while using for 4-5 hours. It seems that my hands will definitely burn if I touch the motor after long use. The air coming from the centre of grill feels hotter too. I feared the fan was defective and will burn soon. But it seems the motor is fine with such high temperature rise. Is it ok? What is the ideal temperature rise of motors? Can I use it overnight without being worried?

    3) The high speed pedestal fan (Modi) uses 80 watts at 205 V, 100 W at 230 V, 110 W at 240V, which I have tested with watt meter, Why wattage increases with voltage?

    4) Suppose a fan comes with 440Volt 4 microF capacitor. What will happen If I replace it with 2.5 microF capacitor and with 6 microF capacitor? Which is bad for motor higher or lower assume in both cases motor starts and runs with no difficulty.

    • https://www.bijlibachao.com Abhishek Jain

      First I should appreciate your inquisitiveness to understand the basics of engineering and efforts to save energy.

      1. The selection of bearing is part of the design part of a particular concern. However, it appears that all fans which are having horizontal mounting are using sleeve bearing. Sleeve bearing is cheaper with less life. Keep a watch on the performance as you may not be able to do anything at this stage. Please advise the make of the fan in which sleeve bearing is used.

      2. Temperature going so high in Modi pedestal fan motor cannot be a designed feature. It means winding temperature may also be going very high and the fan is likely to fail earlier. You should write to the firm.

      3. When voltage is low, the speed of the fan goes down. This is the principle of fan regulator in which the voltage is reduced to control the speed of the fan. At lower voltage, the speed is less and as per the characteristics of the fan, the power consumption is proportional to the square of the speed of rotation.

      4. I am unable to understand you stating voltage as 440V. Single phase system is operates on 240 V. Capacitors are used to start the motor and to improve the power factor during running. There is sufficient tolerance in the design of capacitors and will not cause any problem. For very low value, the fan will either not start or run at low speed. For very high value, there will be over compensation, and not good for the system.

    • Ajay Sharma

      Thank you Abhishek for your elaborate reply. I was waiting for your valuable suggestions.

      1) I found all new pedestal fans by Havells, Bajaj, Crompton for my home has sleeve bearings. We have one old Usha pedestal fan from my father’s time. When I was young I watched him pouring few drops of oils in oil canal once in a year. But in new fans I couldn’t locate any hole to drip oil. Our electrician told me that they can’t be oiled as the newer age sleeve bearings are oiled for life. As I understand from your reply that the newer age fans have plastic body, blade, so they have shorter life. Thus their bearings need no oiling during that lifespan, but somehow I like the transparent blade fans.
      Fans in my shop have ball bearings, and metal body and blades. So I hope they will last for 10+ years at least with heavy use.
      2) As you have suggested I will ask the electrician to replace the local fan with a branded one. I noticed this fault one day, after runnning it for some time, when I touched the motor to engage the oscillation. I was anxious that it might catch fire and throw flames at bed or curtains through the openings of motor. It has 2 years guarantee. But it is difficult for me to run after a company for free service just for a mere fan.
      3) The fan stamp says 90 watts. So I was wondering. Thanks for your explanation.
      4) When ever our ceiling fan capacitor fails, the electrician always replace them with higher ones. My relative saw him doing that and told me this will ruin the motor. The electrician explained, since voltage often drops below 200 so a higher capacitor will keep the motor running at high speed at low voltage. But my close relative told him to change those with normal ones. After doing so I found the fans are running bit slower.

      After reading your article I am interested to buy superfans for my shop as they run continuously for 10-14 hours. But they only manufacture ceiling fans. Is it economically beneficial to replace ordinary fans with superfans for an air-conditioned room? In our locality none keep Superfans, so I want to buy them from online stores. In case of malfunction, can I get them repaired on site by company? I am interested to buy a inverter front loading washing machine by samsung. Is it worthy to have one instead of having a normal front loading automatic washing machine?

      Can you write an article on food processors available in Indian market. There are so many food processors that we feel puzzled. My friend told me mixer grinders are not very much useful rather food processors are must have for a kitchen. We have Bajaj food processor for some time, but it is awfully noisy.
      Are hand blenders worthy? Most user complain about burnt motor when motor was stressed.
      I would like to see an article from you on microwave and induction ovens in future. My question is are they going to cost less than gas cylinder (subsidy cylinder, 1 in every month)? If we start cooking using electricity only (Microwave, Induction occasionally oven) in Delhi and in Patna?
      Thanks and regards.

    • https://www.bijlibachao.com Abhishek Jain

      Hi Ajay,

      Superfans are quite efficient fans and if your usage is long then they can certainly benefit a lot. The only challenge is that they do not have service centers everywhere in the country. They have a 5 year replacement warrant, so they replace fans when it does not work properly and they are not able to help you fixing it over the phone. But the total delay of replacement can be 5-7 days (shipping time). People have had great experience with superfan while using. And it is not that they always go bad. But if they do go bad by chance, then the whole experience is a bit cumbersome. They usually do not send anyone to repair it onsite. And the only place to buy them in North would be online.

      As for inverter tech washing machine: if your usage is high (as in multiple loads in a day as would happen in a laundry) then it makes great sense to go for an inverter tech washing machine. But if you use it just once a day, then you will not be able to get payback of the extra investment that you put in for buying one. The machines are great, just a bit costly (because of the technology).

      We do not have article on food processors yet. But we will try to research on that. As far as microwave and induction cookers are concerned, you can look at these:

  • Scott274

    The power saving is great in Superfan but it has a lot of crucial cons…
    1. As you mentioned, the switch off on the remote does not completely switches off the fan, but rather it goes in standby mode while still consuming about 1.5W power in addition to that irritating led that keeps glowing, many reviews online (on Flipkart, Amazon) complain of this, the off button on the remote is pretty much useless. A zero speed would be more useful (especially in winter to circulate the air and get rid of the cold air pockets without decreasing the room temp further).
    2. They offer 3-5 years warranty (onsite!, offsite!)..YAY!…not so much, remember, your fan is not a light bulb which you can just pull from it’s socket and replace a new one, and anybody who has experience with claiming warranties at service center(s) (which is pretty much everybody!), would know that it can be quite a pain in the butt. In fact one of the reviews (on Amazon) mentions that their warranty terms and conditions are such that they can easily void your warranty anytime, like for eg, you lose or break your remote, they will counter claim physical damage and void your warranty. They can also say they don’t have any stock left to replace your fan and make you wait for weeks..(better keep a large newspaper handy!).
    3. It’s Hi-tech, the old creaking and groaning fans might not be so but they at least keep ticking while taking all the licking for decades…same can perhaps not be said for the new Hi-tech fans like Superfan. It has a sensor microchip in it which will cause the fan to stop (to standby) if it’s blades encounter any obstacle (while still damaging the object), but limit the damage to the fan itself. Now the sensitivity of this sensor may be in question, while using fans we normally tend to keep our windows open…what if Lex Luthor outside decides to send in a butterfly…

    Orbit Green fans seem to be very rare ( I could only find one site online offering a BL30 for some 3k Rs), their availability in local shops is doubtful (although I’ll ask around when I can find the time). Their nearby service centers location may also be a problem (same for Superfan!). Orient Ecotech is too expensive (at some Rs 5k), don’t know if they will last long enough to give any positive returns, which is the whole point of going to all this trouble to change fans.

    • Anjan Banerjee

      Hello Scott274, No BLDC motor is required. The existing AC induction motor can be made superior to fulfill the BEE 5* requirements if the companies are forced to do so. Most of us are not aware of the fact that permanent split capacitor single phase AC induction motors used in fans (ceiling, desk, pedestal, wall or exhaust for domestic purpose) are 30-50% efficient only. So, inherently they are too wasteful in terms of efficiency.

      However, a point to be noted that pump motors and newer refrigerator and air-con compressor motors are more efficient and they are ~70-85% efficient. Induction motors found in Air-con blowers are also 70-85% efficient.

      After BEE implementation the manufacturers has bought 5* fans which have lower air delivery but have the same motor as older ones have. By reducing load on motor they have reduced energy consumption, but this does not change the technical scenario that motors used in fans are wasteful. So only 30-50 % is used for work rest is wasted as heat.

      Now it is clear that the existing motor technology needs to be changed. But instead of bringing radical change in motor technology i.e replacing AC induction motors with BLDC motors, the existing AC induction motors can be improved as super efficient AC induction motors. Currently in Europe, America, Canada newer motors for industrial applications needs to to be efficient by law (see https://en.wikipedia.org/wiki/Premium_efficiency ). Such efficiency scale are not yet implemented in domestic scale motors, but it seems that companies are adapting the advanced efficient technology in domestic applications to attract customers.

      We the Indian customers have to raise our voice forcing the companies to make energy efficient motors. The energy efficient AC induction motors will be costlier for use of copper instead of aluminium in both rotor and stator and more iron in cores. But it will pay back in few years. Also efficient motors will be stronger and thus will deliver more air by using same energy as current motors. If you look at BEE site you will notice that 1200 mm sweep fans have to deliver 210 cum/min air to qualify (see http://www.beestarlabel.com/Content/Files/Schedule-8.pdf ). Most 1200 mM sweep fans deliver 210-230 cum/min, which indicates all fans are only marginally better than minimum requirement.

      In USA I have seen fans whose blade pitch can be changed as per requirement. This is a useful feature. BLDC motors have unque characteristic that their torque and speed both can be adjusted independently also simultaneously. So the feature that I have just mentioned perfectly suits the BLDC motors and should be adopted by manufacturers. By this one can increase blade pitch, decrease motor speed but increase torque. Hence fans will run silently delivering same amount of air as normal speed. Also, when required we can increase both speed and torque to deliver more air if there is more people in room. BLDC motors are versatile, instead of making ordinary BLDC fans manufacturers should look into the matter to dig out more from BLDC motors.

      As far as payback is concerned, we have seen that in Mumbai it ca payback in less than a year is many cases. I am sure Orient Ecotech will also not be for more than 2-3 years in Mumbai. And tariffs are quite high in several places in the country.

    • https://www.bijlibachao.com Abhishek Jain

      It’s a catch 22. To have a market transformation, someone needs to try and buy these fans. If no one buys them, then there will be no adoption and then we will remain as energy inefficient as ever. As far as technical glitches are concerned, the concerned companies must take a look at the feedback and improve.

    • Scott274

      Orbit Green, Orient Ecotech and Crompton Greaves Fontier are not even in the Indian market, so the question of trying and buying is out…company has to advertise and bring them in the market….surprisingly in fans market today in India, energy efficiency don’t seem to be much of selling factor if you look at the best selling fans online. Most product pages don’t even bother mentioning the power consumption in their product specifications.

  • Sridhar

    Dear Bijlibachao team,

    Can you please clarify if we run this super fan from the 12 Volt inverter battery directly without a need for an invertor?

    Warm Regards,
    Sridhar

    • Bijli Bachao Team

      Superfan is compatible with inverter. It can also run on DC, you just have to ask for such model.

  • Vipin Jain

    Horrible Service by Superfan employees.
    I ordered 2 Superfan X1 models in colours White and Brown.
    I was told delivery would happen in 8-10 days as fan was not in stock and payment would be done post installation. I agreed and asked them to process the order at the earliest.
    15 days later when I called them, they said the fans had arrived and would be delivered in 2 days.
    When the fans dint arrive even after 7 days, I called them and they said it was raining heavily and so they would wait for the rains to halt and then deliver the fan.

    Its been 4 sunny days with not the slightest of drizzles around, but still no signs of their employees coming for installation.
    I called them today and they said that the fan is now out of stock and would take another 15 days to be available.
    27 days since I ordered the fans and still they tell me the same thing that I was told on the first day.
    Worst experience ever.
    Would never recommend anyone to buy a Superfan ever!!!

  • jeetendra

    Economic of ceiling fan in india….. screen shot picture comparision are too old, plz arrange to update latest, sheet calculatioc

  • Ananth

    Could you please recommend fans which are silent / almost silent? This includes the noise created by air movement. As a reference, please check Aeratron (http://aeratron.org/), Big Ass Fans – http://www.bigassfans.com/for-home/haiku/ and others like Casablanca, which are super silent. Could you please recommend such silent fans in India.

    • Bijli Bachao Team

      Hello Mr Ananth,

      You can look at Usha Hunter Range or Luxaire (www.luxaire.in). Luxaire is energy efficient as well.

  • Anand Pardhy

    Thanks for the excellent review. Could you please give the list of brands under Super Fan and BEE 5Star rated fans

  • Praveen

    Hello BB team,
    As you have used a superfan model for some time now, can you please tell how much noise this fan makes at different speeds compared to normal fans? By noise i mean any humming or buzzing sound other than the sound of moving air. Is it completely noiseless otherwise?
    Thanks.

    • Nishant Gupta

      I have purchased three superfans and unfortunately all three have been making a clicking noise, in terms of quality these fans are no where close to the likes of Usha and Havells. I have even replaced the motor on one still nothing happened. Moreover they just send the replacement they dont send a technician to replace the faulty part and hence you yourself have to pay the electrician.

    • Bijli Bachao Team

      Hi Praveen,

      We have seen 5 superfans till now. The noise is same as that of any normal fan (of moving air). We had issues with two fans twice: one was fake one was real. Once there was strange sound coming and we put in a complaint with superfan team and we realized that the cap on top was making some sound, which was resolved by moving the cap up slightly. The other issue happened when it started making clucking sound at startup and it also increased with time, but then Superfan team duly replaced it with a new motor as they were not able to solve it on phone. The only challenge was that we could not use that fan for 4 days while the new motor was in transit. Since then (for last 6 months) the new motor has been working properly. Rest all fans have not had any issues yet (using them for more than a year now).

  • Nishant Gupta

    Please don’t buy superfan. Their customer care is just non existent. The product is good overall. Although the built quality and paint finish isn’t comparable to the likes of Usha, Havells and CG. I purchased three X1 fans, one of those is making a noise at low speeds. I mailed them multiple times but they don’t respond. I called at their customer care, they told me to contact the dealer. He told me to write in to the company, although he said he’ll replace the fan motor if the issue persists. God knows what will happen to their 5 year claimed warranty, might be just on on-paper claim, as you have no where to go to claim the warranty.

  • Kush

    Sorry, I meant 300 CMM

  • Kush

    India is a hot country. I am searching for a fan with air delivery close to 300 CFM. Any recommendations?

    • Tapas Deb

      Hi Kush,
      The Superfan V1 model delivers 270CMM which is close to your expectation. It really serves my 180 sq ft room very well. I am loving this fan and hope it lasts long enough.

    • Bijli Bachao Team

      Hi Kush,

      We have not seen any fan with 300 CMM output.

    • Kush

      I have seen that Polar fans Winaire++ model claim a CMM of 295. (On their website).
      Can this figure be trusted

    • https://www.bijlibachao.com Abhishek Jain

      Hi Kush,

      Someone has to really measure the same to tell you if it can be trusted or not. If it does not have BEE rating, then it will be difficult to comment.

    Hi All,
    I bought this Super Fan X1 before 5 months from MK Marketing, Chennai. From the date of installation till date, I have issue in remote. The remote is not working & I raised my issue to the local dealer but this is not fixed. I also raised my issue to customer support but no one had contacted me. As a individual, this company is producing super fan but not super customer service. The noise is so huge when running. (Due to air cut).

    I suggest not to buy this product, kindly go for some good brand…. with good customer service network.

      Just now, I received the new remote via courier. I try to use the remote but still my problem continues. No response from running Fan when I use remote.

      I try to do different testing and found one.
      1. When I switch on the fan and then use the remote for first time, it perfectly works and after that no response from fan while using remote.
      2. I try to use the remote to the nearest possible point – close to the head of the fan but still no response.

      I suggest that kindly arrange a technician for a home visit which will fix this issue.

    what about the long term reliability & build quality of super eff. fans?
    are they as durable as our classic premium fans like Usha, CG?

    • G Susila

      Superfan is built with reliability and quality to last longer. The deisgn’s theoretical calculation reveals 65000 hours of trouble free operation.

    • Abhishek Jain

      Hello mr Patil,

      Super efficient fans are in market for last 2 years only. So long term reliability is something that is still to be tested out (they will have to be in market for 10 years for that).

  • Hari R

    I would like to get comments from the super fan users about its performance in the hot summer.
    Would it give hot air as like normal fans?
    Please share your experience.
    This will help me in decision making.

    • Abhishek Jain

      Hi Hari,

      It’s air delivery is same as that of normal fans.

  • SSG

    If superfans are so efficient and help in so much saving, then why do bigger brands such as USHA, ORIENT, etc. not launch this product ? There must surely be some problem faced by these bigger brands. Does anyone have any information about this ?

    • Abhishek Jain

      Superfan uses BLDC (Brushless DC) technology, most regular fans have induction motors. BLDC is also there in inverter technology ACs. Now even induction motors can be improved to achieve high efficiency. But most manufacturers feel that Indian market will not accept costly ceiling fans. In fact government has funds to expedite development and marketing of super efficient fans, but that is not taking off. You can read more about it on this link: http://www.trust.org/item/20130802094324-4tug3/

    Is it still beneficiual to go for same?

    • Abhishek Jain

      HI,

      It depends on your usage of the fan as well as the electricity tariff in your area. Which city are you from and how much will you use the fan in hrs/day?

    hy abhishek,

    my self tejas from Ahmadabad. ur tips hadhelp me a lot in buying freeze and washing machine. now i am looking for fans for my new home. can u give idea regarding it? i am planing to buy super-fan. which size fan 1200v s 1400 or 48 vs 56 need for how much room area. which size fan need for how much area??? my room is 14*12 and drawing room roughly around 18*14. how to calculate that? i had reads in ur website regarding that but now i am not finding it.
    thank u.
    tejas

    • Abhishek Jain

      Hello Dr Tejas,

      For the 14*12 room you can go for the 56 inch fan. For 18*14 you may either go for two 48 inch fans or one 56 inch (two 48 inch will cover more area just in case you feel 56 inch is not big enough).

    • Abhishek Jain

      You will have to check with Superfan company.

  • prax

    The Superfan is getting kinda expensive, they hiked online price and warranty … but there are no dealers here in Mumbai and courier costs are not going to be cheap and service will also be an issue !
    I just saw an ebay add about Rajvihaan , BLDC ordinary fan under Rs 3000 … there are others too … can u review those ?

    • Abhishek Jain

      Hi Prax,

      I just replied to another person so I thought of copying the message to you as well: “if the usage of fan is good the amount saved using superfan is not tiny. A regular ceiling fan consumes 75 watts at speed of 5. Which means if your fan runs for 13 hours a day, it would consume 1 unit of electricity. A superfan in comparison would consume about 0.45 units saving 0.5 units per day! In 30 days that is 15 units of electricity. In most places in India the tariff is more than Rs 5 a unit and in Mumbai it is almost Rs 10-12 a unit. Which means saving of Rs 75-150 per fan per month is achievable. If one is in Mumbai and buys a fan of Rs 3000, the whole fan will payback in 20 months (all of Rs 3000). And the company is giving a warranty of 5 years!! Even at Rs 5 a unit, the payback is in 40 months (of complete replacement of old fan). And in case you are setting up your new place, your additional cost of buying superfan is just Rs 1500, which means the payback is much less (10 months in mumbai and 20 months or less at any other place).”

    • Abhishek Jain

      Their online price includes courier costs and has extra warranty. When they had 2 years warranty, their price for the model without regulator was Rs 2600. I guess you can still get that price/deal from a dealer/distributor (that was what I was told by SuperFan a couple of months back but you should confirm). For online purchases they have a customer support which tries to see if they can solve the issue on call, if they are not, they just send you another motor (if it is within the warranty period). They have a distributor in pune (a friend of mine living in Navi Mumbai purchased it from there). These are the details:

      Email: [email protected]
      Contact person:Mr. Kanipnath Jawale & Mr. Sanjay Kumbhar

      As for Rajvihaan, their website/ebay link does not provide details on its air delivery to make a comparison with regular fan. They have a 1 year warranty with Repair on Return to Factory Basis.

      Then there is another by Maa Solar (http://www.maasolar.com/products/BLDC-12v-celling-fan.html), it’s air delivery of 160 CMM and 180 CMM is much less as compared to regular fan. And people buying it will not get similar air delivery as regular fan. One of the common complaints that people have with BEE 5 star rated fans is that they do not give air :). Super Fan certainly solves that problem with 230 CMM air delivery (equivalent to a regular fan)

      I am looking forwards to a day when brands like Havells, CG, Orient, Usha, etc start making such fans. It will be whole lot easier for mass market penetration for such fans.

    • Ved

      Same here about larger brands ! thanks for that very detailed reply ! i was talking about courier cost in case of failure.
      Versa drive now sell them on snapdeal at a minor discount. i came to the same conclusion ! and had taken an estimate from that very same dealer.

  • Neelanjana

    The previous condenser of one of our ceiling fans blew up. The mechanic who replaced the condenser said that he has replaced the faulty condenser with a higher capacity one (350W, whereas the previous one was 200W). I’m not even sure whether I’m posing the question correctly to be honest. But if what the mechanic said is true, is it going to increase the power consumption of the fan?

    • Abhishek Jain

      Hi Neelanjana,

      Ceiling Fans do not have condenser. Also 350 W and 200 W for ceiling fans is too high. Typical Ceiling fans consume about 75-90 W. So I would need a little more clarity on the question that you have to answer it properly.

  • Kush

    What is the difference between the 1400 mm size Superfans? i.e. V1 and V7?
    Is it only the remote, or are there other differences?
    Also, is there any source of supply in Mumbai?
    I could not find a Mumbai dealer on their website.

    Dear Abhishek,
    It was very interesting to know about the superfans. I want to know the basic difference between these models of superfan . Super A1, Super X1/X7, Super V1/V7.You are doing a great work. Thx……

    • Abhishek Jain

      A1, X1 and X7 are of sweep 1200 mm (which is size of regular ceiling fan). V1 and V7 are of sweep 1400 mm which are bigger fans. If you have a big room then you might need V1 or V7.

      A1 has lesser air delivery as well as RPM. Works with both remote and switch.

      X1 has higher air delivery and RPM (same as regular fans). Works with both remote and switch.

      X7 has higher air delivery and RPM (same as regular fans). But does not have remote and works only with switch.

      You can check more details over here: http://www.superfan.in/specifications.html

    i will be shifting to new house in mumbai, plz suggest which fans to buy Superfan/BEE Star rated fans ??
    total i need 6 fans for my 2 BHK apt., this includes 2 fans for living room. shall i go for Decorative fans of Havells ?
    kindly advise….

    • Abhishek Jain

      Hello Mr Doshi,

      If you are on tata power or reliance, then you can get the energy efficient ceiling fans from Tata Power/Reliance as part of their DSM program. You can look at their electricity bills or website to get the contact details. From that you can get Havells fans (even the decorative ones) that are energy efficient for cheap. However if you can identify a few fans that will have really high usage (more than 10-12 hours), then I would recommend going for Superfan. Electricity prices in Mumbai have become really high and Superfan can certainly give lot of savings.

    • Dinesh Doshi

      thank you so much for ur prompt reply..
      will certainly check with reliance energy.
      my usage will be more than 10-12 hours, and therefore am confused whether to go for Superfan or Havells decorative fans or from the list of BEE certified top 10 fans ??

    • Abhishek Jain

      If your usage is more than 10-12 hours for every fan, then you should go for superfan for sure.

  • srgunukulasri

  • binu

    what about the availability of superfan in kerala?

  • binu

    hi abhishek..
    when i go to to a shop for purchasing star rated fans, the shop owner highly discouraged me from that.He says so many people having complaint about the speed of star rated fans….these fans have very low speed so the air delivery is very poor..it will be horrible on summer seasons.What is the real fact?please clarify….

    • Om

      Fan power
      varies approximately with the cube of the target air speed .

      The power of the fan is directly proportional to the cube of the wind velocity.

      This has
      very interesting implications for manufacturers of “power saving” fans. If a
      fan produces 230 CMM and uses 70 watts, the same fan at 210 CMM will use 53 watts.

      In other
      words, you can achieve the same thing that a BEE 5* rated fan does, by just
      setting the regulator of your fan from 5 to 4.

      There are a very few manufacturers that actually make genuine energy saving
      fans, but all of them use BLDC technology.

      While it is theoretically possible to increase the efficiency of regular split
      capacitor fans, no Indian manufacturer actually does so AFAIK.

    • Abhishek Jain

      Hi binu,

      You can check this page for more details: https://www.bijlibachao.com/fans/bee-5-star-rated-ceiling-fans-myths-and-realities.html .

      By the way we use Havells ES 5star fan (which is evaluated above) and it gives decent amount of air.

      Hope this helps.

    • Abhishek Jain

      Hello Sir,

      I could not understand your question clearly. Although if you want to run just one ceiling fan, then I would suggest that you go for SuperFan. You would need just 35-40 Watts Solar Panel for it. Even the battery required will be much small. Total cost would be around 2500 (superfan) + 2500 (solar panel) + 2500 (for small battery) so in about Rs 7000 or so you would be able to make a good setup that can easily give you a fan backup for 4-5 hours.

      Hope this helps.

      If you feel that the results are inaccurate, we would be glad to share results from any accurate source that you suggest. Although most of the results are in line with data that is available with BEE.

    Dear Mr Abhishek Jain,

    Excellent work by you. Kudos. As joint family we live in two neighbouring apartments in Chennai. Nearly four years back, I was surprised to see 5 star fans in a store and immediately replaced normal fans with these in three bed rooms after crunching some numbers; the power tariff was much lower then. Recently I became aware of the Coimbatore Superfan and bought 4 nos. at Rs.3000 each. Because my number crunching showed that even if I gave away an existing 5 star fan for free and replaced it with a Superfan, I will get a much better return for my investment than what a Bank Fixed Deposit will give me. The Company that came to install the Superfans at my residence brought an energy meter at my request and I measured the Wattage of the different kinds of fans. I can give you the Wattage measurements and the economics I had worked out, if you don’t mind a long mail.

    Regards.

      Hello Mr Prasad,

      Did you buy a superfan? How has been your experience with it?

      Regards,

      Sir,

      Generally any fan will not give consistent results regarding power consumption over a period of time due to normal wear and tear of mechanical components as well as weakening of electrical & electronic components . Any check has been done after a gap of about 1 or 2 years for checking this consistency since no manufacturer covers maintenance of these equipments.

    • Abhishek Jain

      Thanks for the inputs Mr Sheshadri.

    Dear Abhishekji,

    Its really nice to read a good analysis report on Superfans and I am very happy on this regard because, months back me only reported to you about this Superfan from Coimbatore ….I coul not make any comparison or calculations but I did purchase three Superfans from Coimbatore each costs that time (in April-2013) Rs.3200/-.

    Anyway thanks Abhiji, for your great contributions in this site and I hope there is no doubt for anyone like me….

    Thanks a lot

    with cheers and best wishes

    Thanks to Bijlibachao, I am using superfan and they are really taking less power. My inverter backup time has increased a lot.
    Also, these fan are able to maintain constant speed despite of voltage fluctuations.

      Thanks a lot for the feedback Sandeep. We are glad that you are finding the fan quite useful. Your feedback can surely help others decide.

  • T.Das

    never heard about Super Efficient Fans, can you name some popular models of Usha/ Havells etc reputed brands?? BTW, this test is really very informative for me. Thanks

    • Abhishek Jain

      Hello Mr Das,

      We are glad that you found the information useful. As for Super Efficient Fans, currently none of the established brands are making super efficient fans. This can be attributed to their reluctance in accepting the technology (as mentioned in this article: https://www.climateinvestmentfunds.org/cif/content/push-super-efficient-fans-faces-uncertain-future-india ). There are only few companies that make these fans as we have listed in our article: https://www.bijlibachao.com/Ceiling-Fans/super-efficient-ceiling-fans-in-india-market-analysis.html .
      We are currently using SuperFan (www.superfan.in) which is a super efficient fan by a company Versa Drives from Coimbatore. The video in this article is on how we have set it up in our own place. Versa Drives is a company from Coimbatore that has been making Variable Frequency Drives and Brushless DC motors for industrial use since quite some time. The promoters of the company are quite competent Engineers. They launched SuperFan (which uses Brushless DC motor) late last year (December 2012). So the product is certainly new in the market.

      Hope this helps.

      Regards,
      Abhishek

    The current drawn by the fan at various speeds is not sinusoidal due to solid state Triac type regulators. It is important to use a appropriate digital watt meter that can measure watts with accuracy.

  • Superfan

    Regular fan and BEE star rated depend on the regulators for speed. Various brands of regulators work differently and there are variations from unit to unit and also over a period time. This particularly affects the BEE 5 star rated fans – if the regulator is not matched with fan, even when the user sets the regulator for low speeds, the fan runs at higher speeds consuming more electricity. Superfan overcomes this problem by not using a regulator and speed control is accurately done by either remote or the normal on/off switch.

      I replaced most of the fans in my house with Superfans but I still think the price is too high. The price was justified when it was Rs.2600 but at Rs.3420 currently, its grossly overpriced and will take many years before anyone sees a penny in the form of payback. You need to encourage people to buy your stuff with aggressive pricing.

      Besides that, I don’t know what to do with the old fans, its not easy selling them since new ones are available so cheap in the market.
