How does a governor on an air compressor work? 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.
How do you adjust the governor on an air compressor?
To raise the pressure settings, turn the adjusting screw counter-clockwise. To lower the pressure settings, turn the adjusting screw clockwise. Note: Be careful not to over adjust. Each 1/4 turn of the adjusting screw raises or lowers the pressure setting approximately 4 psi.

At what pressure does the air compressor governor cut-out?
around 125 pounds per-square-inch5.1.2 – Air Compressor Governor The governor controls when the air compressor will pump air into the air storage tanks. When air tank pressure rises to the "cut-out" level (around 125 pounds per-square-inch or "psi"), the governor stops the compressor from pumping air.
What happens when governors cut?
When air-pressure is high enough in the system, the governor causes the compressor to stop pumping air (cut-out). When the air-pressure drops to a certain point, the governor will cause the compressor to start pumping air again (cut-in).

At what pressure should the governor cause the compressor to return to its loading stage?
The governor must take the compressor out of its pumping stage (unload/cut-out) when system air pressure reaches 120 to 145 psi (828 to 1,000 kPa), and also put it back into the pumping stage at a minimum of 100 psi (690 kPa).
How fast should an air compressor build pressure?

Air Governors
Legend tells that if left running on its own, a compressor will keep pressurizing air until the pressure gets so high that everything explodes!
The Structure
Despite how it looks from the outside, the governor is a surprisingly complex device.
