Capacitor is used for both starting the electric fan and improving power factor.

To give a quick start-up for any instrument, capacitor is used in electronics, by using capacitor in the start-up there is a charge accumulation in between the plates of capacitor, which is discharged again and gives a quick start to the instrument otherwise we have to use a very high volatage to the instrument.

The voltage taken by the fan during running has lagging power factor and in order to run the fan we need leading power factor. The capacitor increases the power factor. So we use capacitor in fan to increase its power factor
