Onboard Air

[Antitree_hugger]

Any looked at mounting an air tank above the drive line next to the mufler?

A a matter of fact I did! I did a 3" body lift and I saw all of that "wasted space, a perfect place for an air tank! I would probably mount it to the frame on the crossmember underneath the back seats. That way it is a little more protected.

I have my spare removed from underneath (doesn't fit anymore), and was eyeing up the space where it was for dual air tanks. Not sure where to fit the compressor, though.... I'd like to fit dual batteries in the engine bay, that would pretty much make sure an air compressor didn't fit there. I'd try to fit an air compressor underneath if I could find one that had a remote-able air intake and could stand being submerged.

I have yet to see one, you could probably use a plastic battery box and seal it somehow. and Iam sure you could easily fab a remote intake. I would route it through the "air flap" on the passenger side.

Has anybody though about using the PowerTank sytem? I know they are $300+ but, it seems like a more compact system you could mount in the cargo area? I am considering that as my source of air for my ARB air lockers when I get them.

most likely you would have heat dissipation issues if you put the compressor in a water tight box. my ARB compressor gets REALLY hot when in use.

I don't know if you guys are aware of this, but you can make your own power tank. I have one that I got from my dad that I believe is an old scuba tank. My dad has been using them for about 20 years, long before I ever heard of the power tank. I think he got the idea from a friend of his who is in the fire & safety business. I'm not sure how hard it is to find the tanks, but it has to be cheaper than buying a power tank.

I seem to remember seeing that done in one of the 4 Wheel Drive magazines.

I haven't been diving since I lived on Florida, but are scuba tanks rated for Co2 ?

[rrdstarr]

Having breathed both of those gases before I am sure CO2 would be rated at the same pressure? Been too many years......Will investigate it further.

The only reason I wondered is the constant pressure in a Power Tank. It's at 3000 psi right up until there is nothing less, because the CO2 evaporates and creates air (is there a physics major in the house?).

Plain air in a scuba tank starts at 3000 psi for a good fill, then drops off to 500 when you head back to the boat (although I was always empty when I surfaced.

Here is the writing that is on the bottle. Maybe someone can make sense of it.

There has been quite a few posts on doing your own CO2 tank on another list I monitor. Most people seem to recommend going to a welding supplier or home-brew beer web site.

I had asked my brother about this a few months ago. He's gotten pretty far on certification, and he didn't think there would be any problem with using a diving tank.

That is probably correct because a neighbor of mine who gave me the gauges was using them for a home brew set up in his house. Prior to getting the gauges, the tank just had a hose running off of it for filling up tires. I bought a kit at Sears for about $20 that came with a hose and all the connectors necessary to hook up air tools.

I am told that you can use a welding tank which will hold more air, but is heavier. From the pictures I've seen in magazines of the power tank, it appears to be made of some type of alloy similar to my tank. My tank is pretty heavy, so maybe people aren't using welding tanks because of the weight issue? My tank currently has about a 1100 pounds of pressure in it, but it has been about a year since I had it filled up. I am not sure how much pressure the tank holds when it is full.
