Compressed Air vs. CO2 in Paintball

Learn the difference between compressed air and CO2 or carbon dioxide from paintball pro Mike "Pev" Peverill in this Howcast video.


My name is Mike Peverill. I'm here at Pev's Paintball Park in Aldie, Virginia. I've been playing paintball nearly 30 years. I've played professional paintball with numerous pro teams all over the world. This facility here was built from the ground up for paintball, kind of like a paintball Disney Land.

This is a CO2 tank. CO2's been around since the beginning of paintball. That was the first type of gas that was used to propel the paintball gun. Then it was followed by compressed air. Compressed air is basically natural breathing air, like in a scuba diving compressor, as opposed to CO2, which is carbon dioxide. The difference is, you know, CO2 is an unstable gas. What happens is as it gets warmer and gets hot, it goes to a liquid, I mean a gas form, which can cause an increased spike in what's gonna happen in pressure. As opposed to being in liquid, I mean, you know, which is a different velocity. So, so this was always changing. Compressed air is not changing. So what happens, if you want a paintball gun to be efficient, and get more shots per tank, and not have to fill up as often, you want compressed air. Plus compressed air, the bottle itself, fiberglass, weighs half the weight of this metal heavy CO2 gas filled container. So I mean, a big difference. Imagine being on the paintball field for 4 hours, 5 hours, playing all day long. You wanna carry the gun that's gonna be the lightest, and you're gonna want compressed air. Plus, you don't wanna have to come back and refill as much. Now, CO2 tank, that's the cheaper way to go for your gun. It costs less to buy the tank. This may cost more, but in the long run, it's gonna pay for itself numerous times. Because more shots per tank, better gas efficiency, better accuracy. So that, you know, CO2, every third or fourth ball you shoot, the velocity's gonna drop, 'cause you're shooting so fast, it won't reach your target, it's wasting your paintballs. This one is always gonna be on target, same velocity all the time.
