Thomas TPS-95-125-SINGLE-PORT-UNLOADER Pressure Switch

Description:

The Thomas Pressure Switch 95 PSI ON / 125 PSI OFF with Single Port Unloader Valve is an automatic air compressor pressure control switch designed to start the compressor at 95 PSI and stop it at 125 PSI while unloading pump head pressure for reliable motor restarting. Commonly installed on single-stage air compressors used in workshops, garages, manufacturing facilities, maintenance departments, and industrial pneumatic systems. Maintenance technicians, equipment owners, and system integrators use this pressure switch for compressor repairs, preventive maintenance, retrofits, and replacement of worn or faulty pressure switches.

Applications:

This Thomas pressure switch is designed for automatic control of reciprocating air compressors and features a factory-set cut-in pressure of 95 PSI and cut-out pressure of 125 PSI. The integrated single-port unloader valve releases trapped discharge pressure after shutdown, reducing motor starting load and extending compressor life. The switch includes a manual ON/OFF metal lever and is suitable for a wide range of portable and stationary single-stage air compressors.
