Onboard Air Revisited

Recommended Posts

After messing with tweaking retweaking, Redesigning, and still having problems. I decided to stop being such a cheap a$$ and spend some money,

 

I went cheap with a lincoln Mark VII air bag compressor. It worked great for the lockers, however it would only air up one tire before thermal protection kicked in and I would have to wait 20 mins for it to cool down enough to reset.

 

Well I decided to spend the money on a 100% duty cycle compressor this time, Of course all my custom mounts had to be rebuilt, SIGH!.

 

This is what I came up with. Let the tweaking begin, Any comments or ideas to tweak are welcomed.

 

Thanks

Looks good, what size tank are you using?

 

Tank is the rear bumper. It works out to be about 900 cubic inches of tank (just under 5gal)

Looks like you got it done, but I would have done a lot more with flex lines and push lock fittings. Simply cheaper, smaller, lighter, etc. Just personal preference, I priced some of that brass tonight and holy crap!!

Brass was a little pricey But It was not that bad as it is only 1/8 inch. (looks larger in the picture) If I had ordered all the parts for this compressor the first time I would have bought the 3 way T push locks. But It was a quick swap so I ran down to OSH and picked up the fittings. I think total for all the fittings I used there was like $15.

Ahh, ok, that makes more sense, I lost my scale... ;) 1/2 NPT T fitting was $15!! :blink:

 

100% duty cycle?? What is the CFM of that beast, or is it CIM?? :D

Wow, nice work that looks great. Do you find yourself using it a lot or is it more of a just in case kind of thing? Do you have to run dual batteries or a higher alternator to power it?

 

 

It only uses 19 amps. so 2nd battery and higher amp alternator is not required. I have a planned dual batteries as soon as I find a Good ACR. I have a mean green 180 amp installed.

 

I will use it for my air lockers and for airing up after wheeling. I may be able to run a air impact from it for a limited time , Probably enough to break off 6 lug nuts. :)
