Could I plumb my crankcase vent into the suction side of the compressor after a filter to oil the pump and then put a filter/separator on the pressure side?
For the tank I could probably install a 150psi shutoff switch run to the compressor, or a 150 psi blowoff valve?
When I made some air cannons we also used Air-compressor regulators to regulate the Co2 from the bottles (800psi) down to 100 psi, how could I plumb in a regulator on the pressure side to allow only 150psi and to stop over-pressurization of the holding tank?
