I think its about a $15 part. It might be the one way valve that is stuck, if you turn off the compressor does it continue to lose air? On a reciprocating compressor, compressed air can be trapped over the piston when the compressor reaches the cut out pressure and stops. Larger, more industrial air compressors, may have an entirely different unloader valve setup, yet, if the compressor is reciprocating, and has pistons, you will find one or more unloaders somewhere in the plumbing on that compressor. It will, in many cases, be opened by a toggle extending from the side of the pressure switch as the switch operates, or from an internal mechanism inside the switch that opens and closes the unloader valve that is built inside the pressure switch.

When the tank check valve isn’t sealing tightly or at all, compressed air will continue to bleed out until the tank pressure reaches the cut in pressure setting on the pressure switch, and then the air compressor will start to pump up the pressure in the tank again. Now plenty of air comes out of the pump. That check valve (also known as a one-way valve) keeps the compressed air in the tank when the unloader valve opens. Unloader valve failure — Power lags also result from failed unloader valves. This will effectively emulate the operation of the unloader valve, as any air trapped over the piston will flow into the tank as the tank pressure drops.

If that air cannot escape, significant additional load is created for the start up of the compressor motor when the pressure switch turns the compressor back on and that pressure build up may be enough to prevent the compressor from starting. You can easily test it before you buy it by taking off the 1/4" air line going to the air compressor and putting shop air in the fitting at the compressor. Since I do know… Read more », Thanks!

The pressure switch trips in response to the low pressure, turns on the electric motor, and at the same time, closes the unloader valve. Make sure the toggle lever . This single component can activate an engine idle control, divert air from the tank when it reaches the top pressure setting and can reduce oil consumption by equalizing pressure between the pump and check valve.
