Working on cleaning up my old Brunner compressor to put it back in service.
It works but I want to replace the pressure switch, regulator and wiring so its good for another long while.
The motor is 3HP, draws 18 amps @ 220 according to label.
The pressure switch is ancient and is wired into a T fitting from the tank, with the regulator on the other side. I have previously only ever owned modern oil-less compressors, never had one apart so I am just teaching myself the workings of a compressor.
I need guidance choosing a pressure switch and how things should be arranged. There is 1/4 copper line coming off the existing pressure switch which is not hooked up anywhere. No clue where this should go and I think this is from the "unloader valve"?
If I understand this right I should need a pressure switch rated for 3HP @ 220V good for 90-125 PSI with a single fitting on it. Does that sound correct?
Anything else I should be looking at?
Does the regulator have to mounted off the pressure switch or can it be separate?
