No. The old Ford York compressors had an oil sump that provided lubrication. (As did the GM-A6 and Chrysler Tecumseh). All of the newer compressors are sumpless and rely on oil being carried through the system by the refrigerant. They will self destruct quickly if used as an air compressor.

As for PSI, most AC pressure releif valves popped at about 375psi or so. With no pressure relief or high pressure cutout, they would run until something blew up.

actually they all will pump air and can be used as an air compressor but they need a constant supply of oil into them so they dont self destruct, and youd need to put a pressure switch on it or keep an eye on the pressure and turn ut off manually before it gets too high

This is kind of like reinventing the wheel when a 12Volt, oilless compressor is about $200 that would be designed and built for that purpose. Repurposing an AC compressor correctly could be close to the same price, more maintenence, and less reliable.

just depends what you want to do with it, and how you want it operated. youre right about the oily air, on my samurai i used the ac compressor to become an air compressor, and put an oiler on the intake and a filter onthe discharge side so it gets the oil then dries it out before my air tank. but its quite a bit of work.

i took my yota ac pump(no oil storage) and piped in a tee fitting to the intake. the end was a filter, and the tee was a cap, so everytime i used it, i popped the cap, and let it suck some oil in. it worked GREAT...until i forgot to add oil after aring up like 5 trucks worth of BIG tires.

now ive got an old ford(york i think) i just keep oil in it and it works great.

oh, and for the tee fitting, i used one of the coolant fittings used to flush the cooling system. it has a little cap, and worked perfect.
