On Board Air Build

[jparker]

Hey guys,

I am new around here and fairly new to the jeep spectrum of enthusiasts as a whole. I have been modding my jeep slowly and figured it was time to take a step higher, and actually challenge myself with something other than a bolt on kit. I was thinking on board air would be a great addition to the jeep. I started out thinking that an ARB kit and a tank would be all I need, but upon more research I have read that the engine driven OBA setups are far more "capable" route. So before i just jump in and do this, is there anything on here that you guys could recommend? I've heard that most a/c setups are fairly universal, and i am pretty good with plumbing and how that all works. I was thinking instead of dropping over a grand on buying a kit, that i could salvage an old a/c and buy the extras (Manifold, fittings, etc.) at a hardware store for a fraction of the cost. Any input would be great! Thanks for reading

DIY!
I've done converted A/C compressor OBA systems on my two Jeeps.
The 1992 YJ was retrofitted with a Sanden compressor from an old XJ.
My 1997 TJ's failing A/C system was retrofitted to be an OBA system.

It's very easy to do. If you can screw fittings together and do some simple wiring you can do it.
You can get the in line oiler and coalescing filter at Harbor Freight.

Some pics of the TJ setup...

2.5 gallon tank - helps with speeding airing up and running air tools for trail repairs.



Optional cooler for the compressors output in front of the radiator. (Just a basic tranny cooler that's been re-purposed)

Good help, it sounds like something I will be starting in the next couple weeks. First things first, finding the compressor! Thanks for the input
