An air compressor is a pneumatic device that converts power (using an electric motor, diesel or gasoline engine, etc.)

into potential energy from compressed air (for example, compressed air). In one of several ways, an air compressor increases the pressure by forcing more and more air into a storage tank. When the pressure of the tank reaches its designed upper limit, the air compressor shuts down.

Compressed air is then kept in the tank until it is called for use. [1] The energy contained in compressed air can be used for a variety of applications, using the kinetic energy of the air as it is released and depressurizing the tank.

When the tank pressure reaches its lower limit, the air compressor turns on again and re-pressurizes the tank. An air compressor should be differentiated from a pump when operating on a liquid while pumps work for any gas / air.
