Fans In India Have 3 Blades While Fans In USA Have 4. Here’s The Logic Behind It

[ILoveYou]

Things that happen around us can be majorly divided into 2 categories. One - that happen without any rhyme or reason, and two - that do have a reason but we never really got down to think about it. One such thing is the number of blades of a fan. 

Now you might have noticed, fans come with both 3 and 4 blades depending on the place where they are being used. In India, we usually have them with 3 blades.  But the one's with 4 blades, which are mostly used in the US and colder areas, are not just designed that way to look different. There's a reason behind it.

In US, the sole aim of a ceiling fan is to supplement the air conditioner. Which is why the fan, which is slower than the one with 3 blades, serves the purpose of keeping air circulation in the room. The 4 blades move a large mass of air.

However, In India, the fan is mostly used as a stand-alone appliance creating a convective cooling effect. Being lighter, the fan operates at a higher speed and is also energy efficient.
