INDIA’S MOST ENERGY EFFICIENT CEILING FANS?
BLDC technology in ceiling fans is the latest in India, which led to Super Energy Efficient Ceiling Fans [1]. 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.
Superfan
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 is the only BLDC/super energy efficient ceiling fan 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 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
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,
