i was looking on your site but could quite find my problem. i have a hansa htc 20a compressor. its a silent oiled compressor.
The compressor reaches the desired pressure but the engine never seems to cut out, but the pressure doenst rise above the set value either.
What it does do is leak oil from the rubber seal around the tank containing the engine and it leaks oil from the air intake. it seems to release pressure from the air intake.
i've refitted the rubber seal numerous times but to no avail.
Karl, I would say that you have more than one problem with your Hansa HTC 20A air compressor.
If air and oil is coming out of the intake, then that suggests that the intake valve is compromised, and is reacting to pressure buildup in the system to where it "lets go" at a certain pressure, and bleeds air.
That could answer why the compressor runs and runs but does not shut off. You may think that the pressure is getting to the pressure switch cut out point, but it is not.
The oil that is coming out of the intake is bleeding out with the air. There should not be oil there. That suggests to me that the compressor piston seals are worn to the point that oil in the sump is wicking by those seals in sufficient quantity to leak out the air intake.
You have a pretty sick air compressor.
