I have been thinking about getting an on board air compressor. I want to be able run impacts and air ratchets. I want a fixed mount, not portable. I have been looking, but can't decide. I know I probably need a 100% duty cycle. Probably a Viair. Thanks for any help.

I would like to have a 12 volt compressor. Kinda lazy on making brackets, plus getting the power to pull one isn't a problem. I'll be running dual batteries up front and a D- series battery in the bed. My buddy owns a alternator & starter shop, so I can get 140+ amps cheap.

I'm planning on mounting mine under the bed, but you can mount the tank anywhere you want, as long as it will fit and you can run lines to it.

Does that work like the compressor on a smei truck, like with a clutch so it doesn't load the engine or anything then when pressure drops the clutch engages and it starts pumping air? A compressor that big on a car engine like that can probably keep up with a lot of demand even with that little tank right?

it is an automobile AC compressor. It kicks on when the pressure goes below the set point. And turns off when its pressured up. Yeah it can keep up with air tools. I never had any problems when I had mine. Actually I plan on installing one on my new truck. Those were pics of todds install. I posted it for the guy who was asking about mounting a tank in/on a tool box. I would be happy to answer your questions. But shoot me a PM, so we dont hi-jack this thread.

I didn't want to mess with brackets and pulleys on my new Dodge, so I went with a 12V compressor (Max Air 4.0) I would check around some more before you get a Viair. There are several 12V compressors that are better. Like the Max Air 4.0 and the Extreme Outback Extreme Aire
Complete set up, including tank, etc:

Max Air 4.0 stats:

Extreme Aire stats:

4WDproducts runs the special every few months. I ordered mine back in SEP and since I got back from deployment last month, I am still working on wiring and mounting, mine will be in an 40mm ammocan mounted in the crossbed tool box.

The York is the undisputed king of OBA and will run circles around any other OBA (and some shop compressors). http://www.kilbyenterprises.com/faq.htm
The diagrams on Kilby's site are very helpful even if you don't use a York, the other plumbing is similar(the project heep will have a York...)

The Max Air 4.0 is virtually identical to the Extreme Aire, but a bit cheaper. I am going to model my set up similar to the project Fiery Redhead (part 6) write up in Fauxwheeler http://www.fourwheeler.com/projectbuild/129_0410_red/


Hope that helps
