Hey guys, just thought of a random setup. I was thinking that a small 2.5 gallon keg with one of those 16oz or 20oz paintball gun co2 tanks would be nice and compact for a portable beer despenser. What do ya'll think?

Yeah, I've seen those, but it says that the CO2 comes out at 600+psi without regulation and it takes 3-5 canisters for a 5 gallon keg. That's kind of a pain in the arse. I would imagine 2-3 for a 3 gallon keg... that's still a pain, especially if you've read the procedures for pressurizing without a regulator... anyway... just my 2 cents...

I'm not too familiar with keg setups yet. However, I do know a thing or two about paintball setups...though it has been a few years.

If you plan to go with a 20oz tank, couldn't you just use an inline regulator which is also designed to work with a paintgun? Something along the lines of


Though I would assume that a LP chamber wouldn't be needed.

That's what I thought, though I think the only issue would be that the connectors may be different. That's just a matter of getting adapters. Right?

If you have a regulator where the pressure can be adjusted, just change the connectors. Or if you want to keep using it for paintball, splice in quick disconnects. I'm all for multi-use.

You might have to splice a beer regulator into the line, I suspect paintball guns don't run at 12 psi.

no they run anywhere from 80-300 psi. not only do you need a reg, but you need an expansion chamber to keep the liquid out of the tank

Sounds messy. What I do is take a half full cornie charged to 10 PSI. That's enough pressure to dispense the contents and since there's only 20 pints, it isn't too heavy.

I don't believe adapters will be needed. I used to fill my own p-ball tanks off of a standard CO2 tank. (20lbs? 40lbs? can't remember). If I remember correctly, the threads were the same all around.

If you can keep the CO2 tank cool, perhaps in ice, then the expansion chamber shouldn't be needed. If it gets too warm then you'll want to keep the liquid out.

Though, I like david's plan much better.

I understand needing the regulator, but why the expansion chamber? You don't need one of those for a regular co2 kegging system tank. So what's the difference between that and a paintball tank other than size? Wouldn't the gas line be enough to allow the liquid to evaporate?
