It is so crazy spending a lot of money on Powertanks and other simailar CO2 setups. Here is my CO2 setup.
here is how you can put it together for about $100.00

here is the CO2 tank. I have a 5# tank
I understand it can fully inflate about 10-14 33" tires

here are the "single" gauge regulators.
you only need something simple.

You will need a basic air hose and starter kit.
(don't buy cheap plastic crap)
you can get those at Sears or Menards.
I got a 50' air hose and that reaches each of my
tires on the vehicle.

most places I wheel have air. But, this is a nice
affordable setup to have and it doesn't take up a lot of room.

Links don't work.

[attaboybob]

Thanks....not sure why they didn't work.
these should work

I like where your heads at, as pre-made CO2 systems do seem really overpriced, and I made my own CO2 system, too.

That said, I wouldn't use any of those regulators from that webpage. They all have non-adjustable safety pressure relief valves from 50-60psi. You need 90psi to be able to run air tools, and higher pressure to air up tires faster/reseat beads.

I used the fixed-pressure (150psi) regulator from this page: http://www.offroadtuff.com/CO2Regulators.htm

[attaboybob]

You're absolutely right about the psi.
I may look into one of those rgualtors.

where I wheel, they have air there.
so, I don't use this too much.
But, I do feel safer having the CO2 with me.
never ran air tools It isn't cheap to fill these.

Thanks

What size bottle would be good. How many tires could the 5lb fill?

A CO2 tank would be nice to run air tools off of. I've got an onboard compressor now, but I don't want to do more than air up tires with it(which it's great for) because I don't think I could fit a big enough tank anywhere to benefit from it.

How many wheels do you think you could take on/take off w/ a 5lb CO2 tank w/ a 1/2" impact gun?

I can't tell you for sure. It isn't real easy to tell when it is empty.
I usually refill it before it is completely empty.

I don't have any idea. I've read running tools empties the tank quick!
why would you need to take more than one wheel off at a time?
Anyway, I carry a DeWalt 18v Impact gun for the trail. That I have used to rotate my wheels with no problem with battery life.

The CO2 is a good "back up". A five lb tank doesn't take up much room.
I use the offroad parks air for refilling my tires. I just keep the CO2 for trail use.

I was just trying to gauge how much tool usage I could potentially get with a small CO2 tank. Thanks!

I read somewhere that for one pound of liquid CO2 (like what would be in your tank) it equates to 9 cubic feet at atmospheric pressure, so a 10lb tank would be about 90ft³ of gas... my cheap 1/2" impact gun uses 5 CFM (cubic feet of air per minute) at 90psi, so figure about 18 minutes of use for a full 10lb tank.

(The 150psi regulator I have makes the gun use more air... it's probably more like 6.5 CFM so I would only get about 12-15 minutes - but that's minutes with the trigger pushed down, cranking on a nut.)

EDIT: Also, the only way to know when your tank is getting empty is weigh the tank when it is empty (should be about 16 pounds for a 10# aluminum tank) and weigh it when it's full... If the bottle was filled right, it should have 10lbs added to the empty weight (26lbs). A portable scale, like one that would be used to weigh fish, is a good way to keep up with it.

EDIT: After more looking into it, I have no idea if the one pound of liquid CO2 = 9 cubic feet of gas is correct at all, so please don't base anything off those numbers.

I tried running CO2 for air tools in my garage. Being in the beer biz at the time I had ready access to it. Your air tools will freeze up if run to long. Use shorter bursts. Also, co2 has a lot of moisture. I'll use it for back up, but I don't like to use it exclusively for filling tires or running tools.

i dont understand running a CO2 setup. if its expensive to refill a tank, then why use it to air up your tires? the op said theres air most of the places he wheels, but to the people who use it for their tires all the time...if your going to just air down again the next time your wheelin, why not just use your run of the mill air compressor?

they have this one on the same site that is adjustable up to 130 psi and has dual gauges so you can see when your tank is empty. and its about the same price as the others!!

well in those times when you go to a party and the co2 runds out for the keg you can be the hero and run out to the jeep and grab your co2

I get 5 fills (20 tires) out of each 10# tank with 33" tires. That works out to about $3 per off road trip. The cost is ok by me, as I kept buying and burning up those little portable air compressors.
