Portable Air Compressor Pressure Pump Switch Unloader Control Valve

This pressure switch of this portable air compressor is designed for a single-stage pumping up to 125 PSI but can be adjusted anywhere from 70-150 PSI. This switch features a built-in on/off metal lever and also an unloader located on the bottom of the switch.
