The sizes 9 oz and all the way up to 20 oz can be used for paintball gun. Some of the paintball guns are supposed to be used by the larger tanks. So the size of tank depends on your paintball gun.
A compressed C02 tank or High Pressure Air tank propels the paintball.
Compressed air tanks were around long before paintball.
if u mean the tank that you put your shoulder against and what powers it. no u can get co2 or compressed air (compressed air is better for your gun)
NO! Hpa is compressed air, which is mostly N2. Filling a tank with pure oxygen has a large chance of combustion, which under such great pressures will cause death or serious injury.
Yes, you can use any size tank
NO the gases are different densities and the tanks are specifically made for that gas pressure. If you can afford a gun that needs compressed air then you can afford the tank too.
No. Nerf guns always use springs to pressurize a small amount of air in a small plastic tube, where paintball guns have a highly compressed air or co2 tank in steel or carbon fiber tank.
If you meant "why do you need any gas tank for Paintball": the expanding c02 or hpa is what pushes the ball out of the barrel at high speeds and can be used in reseting the gun. If you meant "why you need a C02 tank specifically": you dont need a co2 tank to play paintball. their is compresed air tankes available. most electrical guns must run on air enless you want to be doing maintenance on the gun after every game and replace parts after 5 games. most non electrical guns also can be ran on air but is capable of runing on co2 but air would keep your gun in better condition. You need co2 or compressed air(nitrogen and compressed air are the same thing) so the paintball can fly out of the barrel and to re cock your gun automatically.
Yes, every few games, you will have to refill the tank, depending on the size. Without it, there is nothing to propel the paintball.
HPA means high pressure air, so it basically means everything you breath in compressed into a tank
3-6 pounds for a 98 Custom depending on the tank size
No, Compressed air lasts much less than a comparably sized C02 tank. This is because CO2 is stored in liquid form, which is much more dense and takes up less space.
