In the hot summers, the only thing we Indians love the most is to sit in front of a fan or cooler and to relax. If we are traveling or are outside, then we understand the value of these fans and coolers. In India, not many families are able to purchase air conditioners and it is considered as a sign of luxury here. So, we Indians are mostly dependent on the fans and the coolers and it’s very important to have a fan that has very efficient cooling and speed. And we will discuss why Indian fans have 3 blades.
I was sitting in my room and suddenly I noticed the ceiling fan and I wondered why Indian fans have 3 blades while the fans in countries like America, Canada have fans with 4 or more blades. This question forced me to do a bit of research on this fact and now I know the answer to this question and would like to share with you guys.

As we all know, America is a developed country and having an air conditioner in every household is not a big deal for them. So, the primary requirement there is to circulate proper air in the room and not the cooling purpose, as they have air conditioners working. Most of the fans in America have a reverse switch which they use in the winters where the fan draws all the cold air from below. Basically, fans in America are multipurpose and they are being used according to the conditions and to make the room temperature comfortable. Having 4 or blades also decreases the speed of the fan and Americans also have fans with lights on them, if fan will rotate fast it can affect the installed lights.
While in India, only a few people have air conditioners in their households and it is considered as the sign of luxury. We are mostly dependent on the fans and coolers for cooling the room. So the only requirement here is to get a maximum amount of air cooling. Fans with 3 blades rotate at maximum speed it supplies a good amount of air. This is the main reason why we use fans with 3 blades here in India.
