on-board air in a WJ

Has anybody put an on-board air compressor in their WJ? If so, can you point me in the right direction?
Thanks!

if you don't mind losing yoru air conditioning, you'd use your stock compressor. Since you're out in devil country, I doubt you'd want to go that route. Most popular way (motor driven) is to hijack a York compressor (any older (pre-93ish) Mercedes you'd come across has the correct one), but I don't know of anyone who makes the crossover brackets to use in the WJ.

You'd prolly be better off going electric & getting a Viair compressor (450 is a good model [1.62 cu.ft/min 100% duty cycle, and it won't break the bank) and a scuba tank and running that through. Would give you the best options on how you'd want it run.

Viair compressor

Whats the difference between the 45 and the 500? The 500 has 50% greater CFM, but I don't know what 33% duty cycle vs. 100% duty cycle means...

My main goal is to be able to re-seat a bead if needed, and I'd like to be able to run air tools in a pinch (although a power inverter and electric really would work fine too...) I'd think that once you got past the install a motor driven system would be more capable and less hassle, but maybe this is overkill. Two weekends ago I slipped a bead and one of the guys had a motor driven system in his Jeep- I was REALLY impressed by it- had my bead re-seated and tire (over)inflated in like a minute. Maybe it's overkill for my needs but that's never stopped me before

I'll have to look if there's room for a compressor in my engine compartment- it's REALLY packed in there with a 4.7....If there is I can have brackets fabricated. I'll write it up if I do it.

They are pretty loud, if its on the inside you will have to yell to talk. What I'm thinking of doing is getting a pancake tank and a Viair 450 to put in my spare tire well.

not super loud...not like an at-home/shop air compressor, but there is some noise, but then again, you'll only hear itfirst when it's airing up the tank, and then only when you go below the required psi....at which point you'll most probably be outside of the truck using your tools or airing up, so it shouldn't make much of a difference anyway.

Noise supression

OK- so I was thinking about how to keep the noise down (again, this is probably overkill)....How much heat do these produce? I was thinking of mounting it under the truck, in which case I'd want to put it in some kind of enclosure to protect it, or at least a skid plate of some sort. An enclosure is an attractive idea because I could add some insulation and really cut down on the noise (try it with your garage compressor- it really helps!) My worry with the enclosure would be generating too much heat. It wouldn't be a big deal to add in a 12v fan to help airflow, but I'm not sure that would be enough. Has anyone seen or done anything like this?
