India’s Most Energy Efficient Ceiling Fans?
From Superfan, India’s first super energy efficient ceiling fan
BLDC technology in ceiling fans is the latest in India, which led to Super Energy Efficient Ceiling Fans . There are at least 27 manufacturers of BLDC ceiling fans with lofty claims like most efficient energy efficient ceiling fans in India/World, highest air delivery, least power consumption, etc.
These claims are deceptive marketing and a few bad apples who employ these tactics in the industry create a bad name for the entire industry and the technology. This article brings out the fallacy and futility of these marketing claims and its ill effects on the public.
As we are a part of the industry, it is only fair to put forth our marketing claims.
‘India’s first super energy efficient ceiling fan’ – Superfan is the first BLDC fan in India and founded in 2012 by Versa Drives Pvt. Ltd, Coimbatore. This claim of being India’s first super energy-efficient ceiling fans is easily verified as there is only one ‘first’.
‘Award-winning model – Super X1‘– Super X1, is an award-winning model. India Design Award 2017.
‘Patented’ – Superfan, power saving ceiling fan, is the only BLDC/super energy saving ceiling fan with BLDC Technology that has a patented technology. This claim is verified as none of the other manufacturers seem to boast this worthy claim. Patent No: 2873/CHE/2009 A
‘Industry first 5 -year warranty’ – We claim to have a 5-year manufacturer’s warranty on the motor and we honor this fairly.
‘BEE 5 star with service value above 6’ – We claim as BEE 5 star rated ceiling fan with service value of greater than 6. This can be verified by the labeling on the product packaging.
‘In-house design’ – We claim to have designed the whole fan in-house and it can be verified by the several patents that have been filed and are welcome to visit our factory at Versa Drives Private Limited, Coimbatore or call +91 94980 56600.
‘Eco-conscious manufacturing and packaging’ – We claim to be following eco-conscious practices, our plastic free, thermocol free packaging is good evidence, the same is seen in design & manufacturing facilities.
Gorilla fans manufactured by Atomberg technologies is another BLDC fan that is reasonably well known.
’Power Consumption – 28 W’ – It claims 28 W, 1200 mm span, 350 RPM, and 220 CMM at the highest speed according to the website, manual, etc. But the fan has a boost mode that operates at higher RPM (400) with higher power consumption (35 W). Upon this observation, a valid question for an inquisitive user would be,
If 28 W, 350 RPM offers 220 CMM then what would be the air delivery at 35 W, 400 RPM?
Let’s do a simple calculation using Fan laws,
Where A1 – Air delivery 1 – Air delivery promised at 28W, A2 – Air delivery 2 – Air delivery promised at boost mode, RPM1 – Speed at 28W, RPM2 – Speed at boost mode
Let us assume an ideal case and give the benefit of doubt to Atomberg technologies. Inserting 350 RPM and 220 CMM and then find what is the air delivery for the same fan at 400 RPM,
Voila!!! It is 250 CMM
If this is the air delivery at 35 W, any wise business would have boasted this in their marketing and crushed the competition, only there is no such claim. In reality, the air delivery experienced at boost mode does not match with a larger fan which can deliver 250 CMM or more. Hence the logical conclusion would be,
“28 W is a marketing gimmick; their fan gives 220 CMM at 35 W, 400 RPM”
‘Most energy efficient ceiling fans in India’ – In their website and at other online portals, they claim to be the most energy efficient ceiling fans in India. This is utterly untrue as there are fans (even in the list below) that consumes lesser power even than their false claim of 28 W. These cheap tactics brings disrepute to the whole technology and these false claims are unwarranted.
‘BEE 5-star rating’ – This is true and verified by labeling on their packaging.
‘Service value greater than 8’ – This claim is untrue like 28 W claim because service value is a ratio between air delivery and input power. They use their maximum air delivery and divide it by 28, which is a blatant
A company run by IIT and IIM graduates employing these cheap tricks is appalling. Moreover, they have a good ceiling fan which can capture the market even by marketing its true performance.
Orient Ecotech Plus
Orient Ecotech Plus ceiling fan has a span of 1200 mm, consumes 32 W with air delivery of 200 CMM at 320 RPM as per the specifications in the website. These fans come with a 2-year warranty and other variants are Ecogale. According to international standards for ceiling fans IS 374 2019, all the ceiling fans should deliver air greater than 210 CMM. Hence these fans are not worth comparing to other fans mentioned here.
Other orient series fans which have BLDC technology are priced higher and so they are not compared here. Even those fans don’t reach the efficiency of Superfan and Gorilla fans (Not their false claim but 35 W).
Jupiter fans have only one claim that is 25 W power consumption. Even their own website does mention any other specifications. This lack of information throws deep suspicion on the 25 W claim as well. A notable feature is that they have 4 blade ceiling fan which none of the top manufacturers of BLDC fans has brought on.
Surya BLDC fans
A Delhi based manufacturer who is well known for LEDs introduced BLDC fans which consume 32 W, at 340 RPM and delivers 220 CMM. These fans are with 2-year manufacturer warranty. This is similar to the performance of Superfan and Gorilla fan at 340 RPM.
Numerous BLDC fan manufacturers are in the market and some of them are Snoxpower, Solowat, and Maxima. All these ceiling fans claim less power consumption but nobody reveals their true technical
The primary use of a ceiling fan is to deliver air, this concept is neglected by some manufacturers when it comes to BLDC ceiling fans. The best designer will design a product that performs with the highest efficiency without sacrificing the output. A part of the problem here is the regulatory bodies such as BEE, EESL, Ministry of Forest and Environmental Affairs and Ministry of Power which does not have strict regulations on a product that numbers over 400 million.
This article is aimed at educating the public, our mission is to replace all inefficient regular ceiling fans to BLDC ceiling fans to save over 10000 MW in electricity demand. We don’t want the public to buy only Superfan but want the public to make an informed choice rather than fall prey to these cheap marketing gimmicks. When a product boasts of sustainability, then the business practices of the product must also be sustainable. Whatever fan you choose, kindly choose a BLDC fan which gives you maximum thermal comfort and consumes lesser power.
This article compares the lower priced BLDC fans. Please contact us with your opinion on these fans if you are a super energy efficient ceiling fan user.
Edit 27th March 2021
Superfans got acknowledged as the highest energy-efficient fans among the other well-known BLDC fans available in the market. It proves that Superfan is the only BLDC fan that gives the desired air delivery at 35W input power with the most minimal energy losses due to noise and heat.
