ac compressor converted to air compressor?

anyone know how or has pics of converting the ac pump to an air pump??

I take it your talking about making a York compressor? Both of these sites have good information and few pics.

I just pulled mine out, dumped out anything in it. Got some fittings pressed on at a local truck place, wired up a switch and used air tool oil in it. 14 gallons of air, 200+ psi daily for 5 years.

I believe what he means is converting the stock a/c compressor and making it fill your air tank. If its not a york, then it is lubricated by the freon in the system. but when you make it fill your tank, it lacks the lubrication of the closed freon system. What you need to do is run an air tool oiler on the air intake side. On the outlet side you need to run a oil/water separater and filter. Its also a really good idea to run another filtering system right where the air enters the tank. If you keep it properly lubricated, it should last you a long time. I dont have any pics but I ran mine for aprox. 6 months before I sold the truck. As far as i know, the kid is still using it. Hope this helps

A friend of mine set his Sanden up just like Andy described and ran it for 4 yrs with no problems. He runs his shit hard too and it was all good

check out my profile for my mazda. I have a factory mazda A/C compressor converted. It is a sanden with a oil sump. Its been abour 2 years not no problems. Only thing i did was install a check valve between my outlet on the compressor and the tank. Since the A/C compressor was not designed to hold 100+ PSI. All i did was tap the fittings in and put airline to it. I check it once a month to make sure there is enough oil. I get 140 PSI in about 3 mins, 180 in 4.

I have a York and love it. I haven't had any problems out of it with the exception of my last one locking up. It wasn't the compresor's fault - it was user error...lol My dumb ass forgot to put oil in it.

Here are a few pics of mine, i know they are not great. But if you need more info and all just ask.











Basically what i did was remove the old fittings for the A/C and tip the compressor for 3/8 NPT. I myself just inserted some push to connect fitting to the compressor. Some people say to use a leader hose due to heat. But i have had this setup for 2 years now and no problems. I do recomend adding a check valve on the supply line due to the compressor not holding 100+ PSI. So the check valve keeps it alive basically. Also i check my oil one a month...or so, i'm lazy and have went 4 months with no problems. I wired the pressure switch one wire to the old wires for the clutch on the compressor. And just gave the other 12V.

ok, heres a question, can I get my stock compressor to do this as well? Its off a 94 LT1 Chevy engine

I dont belive so, I belive that all chevy factory pumps are freon oiled. The Mazda pumps have an oil sump from the factory so there is no need for oiling through the intake line.
