But for the people who are curious enough to come to our blog. This is the real reason. Why fans in India have only 3 blades attached to it nor 4 or 5 like other countries.
Now you might have noticed, fans in shops 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 other countries like The United states of America and other colder areas come with 4 blades in it. Now they are not just designed that way nor there is any religious belief related with it as in many cases. It’s just Science. There’s a reason behind it.
In the USA, the sole purpose of a ceiling fan is to use as a supplement to the air conditioner. That is the reason why the fan, which is usually 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 but are slower than the ceiling fans in India.
