Hi All,
I recently finished up my onboard air setup and have been having issues with my ABR twin compressor not shutting off and wanted to get input from those who are more experienced/have a similar setup.
Heres the main issue: the ARB twin compressor runs until the safety valve on the tank goes off, so I am not sure if its an issue with the ARB pressure switch, or my setup.
My setup consists of the ARB twin compressor pumping into a 7 gallon, aluminum tank (with a stamped maximum working pressure of 150 psi), then into a two-stage filter + regulator combo. All of the lines are with DOT approved 3/8 tubing and quick connect fittings. The tank currently has a 150 psi safety valve installed but ARB recommended I upgrade it to a 155 or 160 psi valve (because the pressure switch is supposed to shut off at 150 psi). I have a 160 psi valve sitting in the garage but I am afraid to install it due to the rated MWP on the tank. I dont believe that I have any major leaks (the tank holds pressure) but I also read that I should have a check valve from the compressor to the tank so that air does not leak through the compressor.
What am I doing wrong? Do I need to replace the tank for one that is rated at a higher MWP? Is it a pressure switch issue?
Thanks!
