From a scientific point of view, the fewer the blades in a fan, the faster it will give air. India is a country with warm climate. That is, the temperature here is higher than other countries, so the people living here need strong wind. This is the reason why only three blade fans are used in most of the places in India.
It consumes less electricity
Few years from today Earlier, the problem of electricity was very critical. Earlier, electricity did not come quickly and even if it did come, its voltage was very low. That’s why fan companies put three blades in the fan, so that it doesn’t consume much electricity and it can run smoothly even with less electricity.
Foreign fans have four blades. The reason behind this is that it is always cold in European countries, there the temperature is low, so there is no need for strong winds. This is the reason why four-blade fans are used abroad, which have slow speed and are mostly used for ventilation.
