CO2 Refill?

[bruce p]

What did he have for an OBA system - an ARB compressor?

Don't know, I didn't look under the hood. Sounded like the thing made alot of noise but didn't do much. Before I got a co2 system, I have bummed air from other OBA guys who seemed to have much more efficient systems.

Anyone in the Arlington, TX area
Kimbrough Fire Extinguisher will charge CO2 tanks,
about 15 for 5lb, 18 or 18 for a 10lb and 22 for a 20lb.

just picked up a 5lb Alum tank from them for 75 also.
Ended up with a new one since the guy that brought it in was in a hurry, so they just switched his tank out, Lucky for me HI HI

[dr.dirty]

can i fill a scuba tank with co2?

Hey, thats some really great info thanks.

ok im getting really interested in this. I was going to do another thread, but think ill just add on here.
http://www.beveragefactory.com/draft...anks/co2.shtml one of the #15 would be plenty for what I will be needing, but might be just too big for inside a jeep. Does anyone have a write up on using one of these tanks? Or is it basically what Stu has on his site? maybe i just answered my question

I ended up with a used 10# aluminum, and it lasts at least three or four trips. And it fits inside just fine.
I know it doesn't sound like much, but in the summer, I use it to blow out the inside a little after I fill up. I'm sure it will last more, I just like to make sure it's almost full. I weigh it before I go each time as well.

This is the least expensive way to go, that site seems to be cheap. The only other suggestion I could make is the pre-set regulator from Williams Balloons. http://www.williamsballoons.com/ It seems to stand better against the common freeze lock. I've been using the 125psi, and surprisingly I can fill up all four tires at next to freezing temps. Your local airgas can order the valve if you don't want it online. And they are cheaper than the variable regs.

Those tanks will work and if your building it your self highway420 is right about that valve. I know people that have used the Williams Balloons valves with much success. Make sure you get one thats 125lbs. That will run air tools if you desire and also fill up the tires much quicker. Also check out

Oh yeah, two more things....
There is an insert that threads on the inside of the valve on the tank, that makes a 'fixed' seal so you don't have to use the fiber washers every time you put the reg on. It's a brass piece with an o-ring pressed in the front of it. It just stays there, and when you put the fixed reg on, you don't need a wrench to tighten it. It works by hand.
Second...
Tavern Service, where I get mine filled, also set me up with a sort of protective cover for the threads and dust when the regulator is not on...I have my tank on my carrier more often than inside. So I asked for something to cover it.

It's basically a nut with a hole, I know, just wait....I said the same thing.....He proceeded to put a penny in it and then threaded it on the valve. Perfect!! It works great. The whole enchilada cost about 100 by the time I was done. Still cheaper than buy a new shiny Powertank.
Harbor Freight,(the Candy Store for Men) is my supplier of the rest of the parts, i.e. quick releases for the air, and hose.

one of my buddys said that these tanks freeze up and dont fill up tires that fast. EVERYONE PROVE HIM WRONG!
I thought these tank, since there built for US, have special regulators so they dont freez up. am I right? Also anyone have an air tank a fill up some 35s?

I think he may be talking about the regulator. I have heard of that happening but not the tank freezing. There are regulators out there that will freeze. Thats why it's important to get the right one. With mine I fill my 33" tires from 13psi to 25-30psi faster then any compressor I have used. Valve has never frozen.

That's why I got the 'fixed' regulator.
I went a snow run in Frazier a couple weeks ago, and by the time we were finished, it was dark and close to freezing if not already there, and I still filled all four from 14ish to 35 in less time than the pumps that were next to me, AND without freezing. Don't get me wrong, the valve/hose had plenty o' frost, looked like it was about to freeze over, but never did.
The preset regs only have minor moving parts,if any, just a strong spring and some seals. Where as the variables with the gauges and adjusting valve body, have more 'things' to freeze up. It's also bulkier and more likely to get damaged, since it sticks out.

Just scroll down for a desc. of what I have....
Others have seen it on the trail and have liked the combo.

Tell you what, though.....in the summer temps... whooohooo....boy, it's perfect. Just get the sun to shine on top of the tank....and presto...auto defrost!!

But that last fill in the really cold temps sold me on the setup...I was hesitant at first, but it proved itself worthy, and that's what counts.:thumbs_up

so you think having a fixed regulator is better? I mean I think 98% of the time I will be airing up where its warm. I mean come on its California! I just thought having the regulators would be nice to have. Do they tell you how much CO2 is left when its getting low?

Also do you have any type of gauge that tells you how much PSI is in the tire while your filling, or do you have to keep checking?

No matter what your regulator is going to frost. Remember CO2 is liquid dry ice. If your tank is clean and there's no moisture in it you shouldn't have any issues. The clogging comes from the CO2 freezing the moisture(water) in the tank.
There are regulators that show (in psi) how much CO2 is left in the tank. The problem with the beverage type is that the outlet pressure is really low and it will tank a long time to fill the tires. Then there's the ones from Powertank etc. to much $$ for my taste.
I weigh my tank and use a regular tire gauge to check pressure.:2:

thanks, Im looking at getting a Source http://www.wheelersoffroad.com/co2systems.htm
from Brett at Offroad Werkz and just want to make sure its what im looking for. They are way cheaper than Powertank!
