Old Air King compressor trips breaker at about 60 psi
I've got an old Air King compressor probably from the 50's or 60's that has developed a problem. This is the type of compressor that runs continuously and uses a bypass valve to allow the compressor to 'freewheel' when it reached full pressure but the motor continues to run.
My problem is that now it will start up and run but as it builds up pressure it puts more and more strain ion the motor. It is a one cylinder compressor and you can see the room lights pulsing in sync with the compressor.
At about 60 psi the back pressure is too much and the breaker trips.
I really like this old machine and would like to fix it. Any suggestions?
