Chicago Pneumatic Single Stage Compressor Pressure Switch - 1312100455

A compressor pressure switch turns the compressor on when it hits the lower pressure setpoint and turns the compressor off when the upper setpoint is reached.

The unloader valve is swivel based and can be adjusted to fit the unloader tube if needed. The pre-set cut-in pressure is 105psi and the cut-off pressure is 135psi providing a 30 psi pressure differential. The 1312100455 utilizes 4 threaded 1/4" female ports for the safety valve, gauge, and tank connection. The switch also includes a red on/off switch.

The pressure switch needs to be replaced if the compressor does not turn on at the lower setpoint or does not turn off at the upper pressure setpoint (causing the safety valve the blow on the tank). This results from the contacts being welded together over time. If you find your pressure switch is constantly leaking out of the unloader line, you should consider changing the check valve instead.

This part number may also be listed as 1312 1004 55 or 1312-1004-55. This OEM switch was also commonly used on Quincy, BelAir, Atlas Copco, and NAPA air compressors.
