Manually adding oil to an A/C compressor.

What kind of compressor is it? The older York compressors had oil in them, there is lots of info on the web about running air conditioning compressors as air compressors, I am in the middle of makeing a York one my self. Things to start with would be doing some search's for "Onboard Air" lots of off-road guys do that to have air onboard with them. onboardair.com has some good info on it. If you are painting the hard part is going to be a septerating the oil from the air before it gets to your paint gun. Putting a tool oiler or something like that on the inake side will keep the oil going into the compressor. You are also going to need a tank and a regulator to keep the preasure right for the gun.

...and a ton of oil right into your paint, no matter how you slice it.

Go rent a proper air compressor.

I`ll rent a compressor. For knowledge purposes, how can I filter out the oil? I have a 3-gallon tank. Should the vaporized oil sink to the bottom of the tank?

I did a search and found one person who used a water separator inline with the discharge from the compressor. He rigged up a device with copper tubing and a Classico pasta sauce jar and it works like magic. He got the design idea from a friend that used to be a mechanic on submarines. No oil comes out after this new filter, only a tiny bit of atomized oil, which the water separator can’t handle.

Should a densely pack filter paper (like dusk mask) filter out the remaining oil? Rick

1989 Nipindeso compressor.

I did a search like you said and found great York informatiion. For a rotary type, one person who used a water separator inline with the discharge from the compressor. He rigged up a device with copper tubing and a Classico pasta sauce jar and it works like magic. He got the design idea from a friend that used to be a mechanic on submarines. No oil comes out after this new filter, only a tiny bit of atomized oil, which the water separator can’t handle.

Question: Will the atomized oil ruin the paint job?

[[Putting a tool oiler … will keep the oil going into the compressor.]]

I assume I can just hand spray fluid in there once in a while, correct? Rick

Uhh... you're using this for PAINTING? How are you filtering the compressor oil out of the air before it gets to your spray gun? If you're not, you're going to be in fish-eye hell.

But to answer the question, there IS no other way to oil an AC compressor (unless its an old York or Chrysler with an oil sump) for use as an air compressor. But most of the time when this is done, its for off-roading- filling tires, running air tools, and other applications where having oil droplets inthe air is not a problem.

Yes.

Okay I seemed to have gotton most (99.3%) of oils out of there. I have a 4 stage filter papers and in the middle I used a dissicant crystals which says it`ll absorb oils. The final stage is 2 more filter papers. The air resistance is low so that I need to get an air flow regulator to bring the flow down. I rigged the filter setup to resemble this one. Here take a look.

Below the website I got it from.
