A ceiling fan on the other hand requires 75-80 W. Due to its elevated position and its ability to cover a larger portion, it requires greater power. Factors on which the power consumption of a ceiling fan depends are:
Height of Ceiling: For proper air flow in every room corner, you need to previously check on the ceiling height. Accordingly, you need to choose the apt ceiling fans.
Motor: Old fans run on motors that are not technologically upgraded. Therefore the price of old ceiling fans might be low but the power they consume is maximum.
Presence Of Dust On Blades: Continuous usage and improper maintenance accumulates dust particles on blades. This reduces fan speed.
