SQUARE D 4 Port 135-175 PSI Air Compressor Pressure Switch 9013FHG44J59M1X Square D

Brand new Square D brand, Pumptrol 4 Port air compressor pressure switch, model: 9013FHG44J59M1X 135-175 PSI with unloader control valve and On / Off switch. This pressure switch is designed for a 2 stage air compressor pumping up to 175 PSI but can be adjusted anywhere from 100-200 PSI. This switch features a built in On / Off metal lever and also a unloader located on the bottom of the switch. The unloader is used to unload head pressure off the compressor pump for a load free start up.
