There is more than one purpose for the oil in the capacitor. It is used to remove any air voids and it helps to cool or remove the heat from the capacitor windings. When they reach their discharge capacity, these windings tend to generate a lot of heat Oil-filled capacitors supplied today contain non-pcb oil and are a ul recognized component. Oil-filled capacitorsare only supplied with ballasts where the capacitor operating voltage cannot be satisfied by dry film capacitors. When required, the capacitor discharge resistor is connected across the capacitor terminals

Oil capacitors function over prolonged usage periods without losing capacitance value. Thus they play a vital role in maintaining the speed of fans.
