On board Air

I'm trying to turn my AC compressor into an air compressor for on board air. I have the rest of the setup figured out but I'm having a hard time figureing out how to do this part. Don't I need to keep the compressor 'lubed' so that it will not freeze up or just refuse to work? I'm not sure exactly how an ac unit works so I'm feeling kinda stupid on this question. I know that the compressor is out of freon (sp?), it will not turn on...Im guessing the freon acts as some type of lube for the compressor. How could I make this happen w/o having freon in the lines going to the tank and out of the hoses?

In a normal system, the freon (or rather the lube added to the freon) is the lube for the compressor. There should be a safety on the AC so it won't turn on if it's empty. You should be able to put 12v to the wire goin to the compressor clutch and force it to engage (that's how you turn on the compressor wth an OBA setup), but be careful to not fry it if your system is empty. As far as converting it to OBA, it's up to you to keep the compressor lubed. When I did it in my XJ with the factory AC compressor, I just poured oil in the compressor occasionally. A better way to do it is with an air tool oiler. You'll also want an oil separator after the compressor, as that type of compressor blows out a lot of oil into your lines. Make sure the output coming from the compressor is a high temp rated hose too.

Hope that helps. I'm waiting for the AC to die on my Jeep so I can convert it. I hate electric compressors.

That's what she said.
