Onboard Air??

I'm looking at installing an AC compressor to use as an onboard air compressor. The compressor is a stock AC unit out of a "98 grand cherokee charged with Freon 134.

There are several good writeups on this but none of them address the compressor lubrication. I was under the impression these compressors were lubricated by the freon running through them. if that is the case, how do you keep them from burning out without some type of oiler on the intake side?

Any suggestions or advise?

My rig had the jeep compressor running for years by just hooking the intake side to the crankcase breather, this grabs slightly oiled air. I hooked my gm one the same way and it's working so far. I would recommend a drain on your tank as it does get oil and water build up.

Mine is the compressor run to a pressure switch, then to the tank, power is key on to switch, then to the clutch.

I just installed in inline oiler before it goes into the compressor, then an oiler seperator on the discharge of the compressor

look for a York compressor they have a separate oil reservoir so they don't rely on oiled refrigerant for lubrication.

i have made a simple oil reclaimer out of a quart size propane bottle which catches oil coming out of compressor and bleedes it back to the suction
