So my A/C doesnt work anymore. I am running a 5gal air tank on board right now, but was thinking, I've heard of people converting their A/C compressors into air compressor. Anyone have any info on this?

here is a link I found on google. hope it helps.

AC compressor is lubricated by oil fluctuating in AC the system. So it will die rather quickly....

You need dedicated air compressor.

You would think , but it won't.. I know of 1 thats been in a shop for years now, It's well used and still works perfectly...Which its a Ford Compresor so i dunno, that may be better for this sort of thing

Ford compressor? Do not know much bout fords, I just remember some ancient US designs had actually AC compressors with piston and crank, just like air comperssors.
Denso compressors are "swash" plate multipiston design and they will die with no lube easly.

I used to have a better link but I can't find it now...

You want a York.

I have seen it done on a lot of Jeeps, and the York compressor is definitely the way to go. 4WD hardware actually has a kit for this. I saw one guy who used his roll bar as a tank!

Good luck!!

Using the Ford AC compressor might be a little too redneck for this board but it works great, I promise ya, I have seen and used them for years

hosh

i think the "ford" compressor is actually a york

That is correct, they were used in a lot of vehicles. Fords and Jeeps I know for sure.

York is the only way to go. Preferably, a york 210 model. Usually found on older Volvo's. they can flow like 10 cfm and the oiling system is self contained, if i remember correctly you can just use 10 w 30 engine oil. Lots of people have done this on jeeps but i would really like to do this on my 91 ext pickup 22RE. here is a link with a lot of info and specializing in custom kits and accessories for onboard air with a York compressor. Even sell new compressors. Hope this helps some.

the york 210 refers to 10 in? displacement per stroke 206 = 6in?, 209 = 9in?

there are 1728 in? in a ft?. so multiply displacment by rpm and then divide by 1728 get cfm
york 210
3000 rpm * 10 = 30000/1728 = 17.36 cfm
1500 * 10 = 15000/1728 = 8.68 cfm
york 206
3000 * 6 = 18000/1728 = 10.42
1500 * 6 = 9000/1728 = 5.2 still more than any electric onboard compressor and more than some garage compressors.

They can be ran up to 6000 rpm but i wouldn't suggest it for extended periods. And yes 10w30 is fine for oiling.

they can also produce quite a bit of pressure so you need a cutoff switch and blow off valve.

I can get used york compressors. I mostly see 206's and 210's.

If anyone is interested let me know.

hosh

sorry about the ? on my screen it was a small 3 for cubed

I fabbed up one of these on my FJ40 and ran it into a fireman's tank. It worked great. If you are still looking for pointers let me know.

I'd stay away from putting compressed air into anything that might get cracked. (Roll bar or bumpers especially) I'd also keep the tank not pressurized while not in use. Hate to get in a wreck and shoot that guy off like a rocket.
