Question about Air Tools & Compressors
I have a 4HP 12 gallon pneumatic air compressor that is not blowing out air. The compressor motor is still working. Cannot make out the model because air compressor is old and labels are either barely readable or faded out. It is an Air America Type model. Could you please advise to where I should start to find problem. Also, no familiar with connection compressor pump. Compressor was given to me in this condition. The pump has an auto and off selection with 4 terminals: end terminal connections are L1 and L2 and the middle terminals are T1 and T2.
Is it building pressure in the tank and just not going out your air hose ? Or is it not building any pressure in the tank?If it is building pressure than the problem is narrowed down to your outgoing channels which does simplify things.(-8 Either something has got clogged in the outgoing airway, or there is a good possibility that the pressure regulator needs new parts if you can find them or just replace it. Have you tried turning the regulator output up or down? It may be stuck all the way closed which would shut off the air coming out.If your not building any pressure then the piston/s may need new rings or the cylinders are scored and need machine work. That part works basically the same as the piston/s and valves in an automotive motor. Except instead of pulling a fuel mixture in and igniting it for power and then pushing out the exhaust, it pulls in air and pushes it into the holding tank compressing it to X# of psi with the assistance of a check valve.

Check the valves. They could be breathing in and out and not sealling.
