How much PSI does the A/C pump have?

J.McDonald Knives · 10-24-2008, 12:24 PM

Not sure if this is in the right forum but I was wondering how much PSI the A/C pump has. I don't use the A/C but have an idea on how to convert it to an air pump. Got the idea from Junkyard Wars and was going to pipe it into a tank. I want to use the A/C pump because it saves room and I don't have to worry about finding a place to mount a pump and running all that extra wiring. I was going to use the custom bumpers for the tank.

usually the 4x4 people i know use a york compressor. i think the Subaru one is oiled form the freon and the york compressors are either oil less or have an oil system like a car

I might just have to see if they make a York that will fit in place of the A/C pump.

almost all A/C pumps are oiled from the freon (sp?) if the pressure of the freon is to low the compressor won't even kick on

The high side pressure can normally be from 150-300 depending on the temperature and a/c load, so no problem filling tires or running air tools.

You can get an in-line oilier & filter meant for air tools and put it on the intake site to make the compressor last longer. Then you just need a pressure switch to tun the pump off over a safe psi limit or a safety valve (or both) and wire it from a dash switch to the compressor clutch. Then make an adapter to fit a quick release air fitting and your good to go.
