It has almost the same components as a conventional compressor but there is, of course, a few main differences. A frequency driven compressor has an integrated inverter and often a more advanced control system. The inverter adjusts the motor speed to the actual air demand. This is controlled by a sensor that measures the system pressure this is signaled to the controller of the compressor. The controller registers the pressure and sends a signal to the inverter which regulates how much air the compressor needs to produce in order to keep the set pressure.
