I have seen the Ultimate Air setup, looks cool, but pricey. Why cant a guy just go get a regular 10# or 15# CO2 tank have it filed and put a regulator on it? It could be done for next to nothing..

yes

Yes you can. But don't get a CO2 regulator as it will not provide a high enough flow rate.

I think a regulator from a welding supply store works.

I'm using a Nitrogen tank for mine. Works well to run air tools, allows air shock adjustments on the trail (up to 450 PSI), and runs the ARB solenoids. I chose this route strictly out of laziness because I already had the tank and regulator laying around. Well, actually I had to buy them to set up my air shocks, but I didn't want to buy CO2 also. I don't know how long the nitrogen would last if I started airing up big tires, but filling trailer tires and running air tools gives me PLENTY of life on a fillup. Refills only cost $12 too. I never need to air up big tires because they ride the trailer home and stay at 3-4 PSI...

This is where I got my stuff for my setup. Good prices and selection.

Can't more nitrogen fit in the tank than CO2?

From what I've heard, something like 800lbs for CO2 vs. 1200lbs of Nitrogen in the same tank. Can anyone confirm?

If that's the case then nitrogen would seem like a much better choice in regards to time between refills.

in the same size bottle, you'll fit more C02 than nitrogen.

When compressed CO2 will turn into a liquid and produce between 800-1100psi

but nitrogen is a cleaner gas and won't freeze up your air tools
its also more consistent (i used to play paintball)

The nitrogen bottle comes fresh with about 3200 PSI, but as stated above it does not last as long as CO2. The liquid CO2 boils off to maintain steady pressure for the life of the charge. Once all the liquid boils off, then the pressure drops very quickly. As long as there is ANY liquid remaining, the CO2 pressure will be above 800 PSI. With nitrogen, the pressure continuously drops throughout the life of the charge.

Excellent information.

We'll it certainly sounds like there isn't a clear cut winner in the CO2 vs Nitrogen battle.

Having the option to fill up the air shock reservoirs, consistency and not freezing up the air tools sounds like nitrogen is a good choice. I guess just getting a larger tank to balance out the life of the charge disadantage would solve that.

this is what i use with my co2 tanks

X-2, I also have no problem freezing up air tools with CO2.

so sorry to hyjack, but if i buy that fixed regulator from polyperformance, and hook it up to my co2 little welding bottle i should then have a good onboard system?, also does the bottle have to be standing straight up, or can it be at and angle?

depends on how big it is, i used a air grinder and a 10lb co2 bottle and it lasted about 10 min of continuous use. and yes it needs to upright or you will blow out the liqiud and not the gas.

ok so is that regulator from poly performance, my best bet as far as the regulator goes?

im sure there are better ones out there, but not at that price. mine works fine.

I get Co2 bottles from a friendly barman, they use it to get beer out of kegs, and the brewery just supply all they need.! :D

I weld with it, run tools and fill tyres on the trail. No problems at all.
