Yes it’s true the fans that run on bldc motor can save upto 65% if energy. I am using gorilla fans nage by atomberg technologies. This fans consumes only 28 watt electricity at 5-speed, while on the other hand normal fans consumes about 75watt. It’s means you can ran upto 3 gorilla fans from a power consumption of normal one. This fans come with remote controls and also have features of sleep mode. The company provide warranty of 3yrs. If your daily usage of fan is 12 hrs or more, I recommend you to replace with this model. It is easily available at amazon.in.
