What Shuts Off An Air Compressor?

An air compressor shuts off due to the activation of a thermal cutoff switch wired to the temperature sensors inside the compressor. These sensors monitor air intake, discharge temperatures, and oil temperatures. When the temperatures exceed safe operating levels, the thermal cutoff switch is triggered, cutting off power or stopping the compressor until it has sufficiently cooled down. In most industrial compressed air systems, this safety feature prevents potential damage to the compressor and ensures safe operation.

What Psi Is Shut Off On Air Compressor?

The shut-off pressure on an air compressor is the maximum pressure setting at which the compressor will stop running. For example, if the air compressor has a shut-off pressure of 120 PSI, it will automatically stop running once the pressure in the air tank reaches this level. This prevents over-pressurization of the tank and ensures safe operation. The shut-off pressure is typically set by the manufacturer and can vary depending on the specific model of the air compressor. In the given example, the shut-off pressure is set at 120 PSI, meaning the compressor will kick off (shut off) when the pressure in the air tank reaches this level.
