An air compressor governor is a pressure-relieving device that is installed on an air compressor. It is designed to protect the compressor from overloading by automatically shutting off the unit when the preset maximum pressure is reached. The governor cut-out settings determine at what pressure the unit will shut off.
The recommended cut-out setting for most air compressors is between 95 and 125 psi. However, it is important to check your specific compressor model's manual for the correct settings. If you set the governor too low, it can cause damage to your compressor. Conversely, if you set it too high, your compressor will run unnecessarily and waste energy.
