The picture above is a new cat air compressor. Notice the silver part at the top and front of the compressor head. That is the air pressure governor. The compressor builds air pressure and the governor controls the system air pressure limits. When 120 PSI is reached, the governor bypasses the compressor so that it stops pumping air. When the system pressure falls below 100 PSI, then the governor enables the compressor and the compressor rebuilds the air pressure back up to 120 PSI.
