A while back I saw some posts about people doing on board air. What compressors are you usaing and wher are you mounting them? I'm checking on a few threads at TDR but looking for a little more input. Also how big/where is a good place for the air tank?

 

I am using an extremeair from www.extremoutback.com with a 2.5 gal tank. The compressor is 100% duty cycle so I didnt think I needed a larger tank and dont but if you use less than a 100% duty cycle compressor a larger tank would probably be a better idea. I also dont run tools with it just for the horn and tires.

Kilby www.kilbyenterprises.com makes a bracket kit for a york compressor that fits under the hood and is belt driven.

Oasis makes a nice one too but they are expensive http://www.oasisoffroad.com/products.html I think they use a York compressor that is electrically driven but not positive.

I have my compressor mounted on a bracket on the frame rail directly behind the cab underneath the bed. Mine fits just right there and my bracket sets it up high out of harms way. Tank is on the other side of the truck.

 

Seeing as you have a 2001, Id be in contact with kilby enterprises for an engine driven OBA kit.. not cheap, but, IMHO, the best on the market..

The link for Extreme should be http://www.extremeoutback.com
(There is an "e" missing)

Thanks for the link BarryG, they have the tank I have been looking for!!
I have a 12 volt Viair 450C (still not mounted yet). It is not a heavy duty compressor for a work truck, just something to air stuff up and run tools for a little if needed. I am going to put the compressor in a battery box and mount it on the frame somewhere.

Check out this guys website on the air system he put on his Ram 3500. It is a 12V compressor mounted under the rear seat, with a 7 gallon tank on the frame. You have to see his "power distribution center".

So what is better? A belt driven or electric? What are the pros's and cons? Not sure about giving up the room under the hood, and how long can an electric run with out killing a battery, So in a since the engine might need to run either way??

 

Sorry about the messed up link.

Pros of electric
cheaper
no room lost under the hood
more mounting options

Cons of electric
many are not 100% duty cycle
many do not put out high enough cfm for tools to run very long
some can use over 150amps at full load so you may need to run the truck anyway

Belt driven pros
some can really crank out the cfm
100% duty cycle

Belt driven cons:
more expensive
truck must be running and for high cfm may need a high idler
lost space under hood

Am sure there are other pros and cons of each. Really will depend on what all you are going to use it for. If just for a horn and to fill tires once in a while electric lower duty cycle will work fine. However if you are wanting to run tools belt driven is better.

I think the belt driven are better but was just more than I needed so I figured why spend the extra money and fill what little space is left under the hood. Just wasnt for me and my needs

 

Thank for the info. I guess if an emergency came up, an electric would run a tool, but you wouldn't be able to run it continously. But then in an emrgency sometimes anything is better than nothing. Guess I'm gonna check the electric kits. Thanks.
