Industrial 25A-140PSI-175PSI-1-4in-Port-4Way Pressure Switch

Description:

The Air Compressor Pressure Switch is used in compressed air systems to automatically start the compressor at 140 PSI and stop operation at 175 PSI to maintain system pressure within preset limits. Commonly installed in reciprocating air compressors, shop compressors, pneumatic systems, and industrial compressed air equipment requiring automatic pressure regulation. Maintenance technicians, compressor service providers, and equipment owners use this switch for compressor repairs, pressure control replacement, and compressed air system retrofits.

Applications:

The Air Compressor Pressure Switch is commonly used in industrial air compressors, automotive repair facilities, manufacturing plants, woodworking shops, and pneumatic tool systems where automatic compressor cycling is required. The 1/4-inch four-port configuration allows connection of pressure gauges, safety valves, pressure relief devices, and unloader valves while the 25A rating supports direct motor switching on many single-phase compressor applications.
