WHAT IS C02 AND NITROGEN?
Co2 and Nitrogen are propellant gasses that paintball guns use to shoot a ball. Co2 or carbon dioxide is an inexpensive gas that stays in a liquid form in a tank connected to the marker, as the gun is discharged the liquid boils into a gas, this gas is what the gun uses to shoot the ball. One problem with Co2 is it reacts to temperature in the form of pressure variation. At 70 degrees a Co2 tank has about 850psi in it, A 50 degrees its about 650psi. In summer it is very stable, but in very cold temps low pressure can cause performance problems, however it is still the key propellant in most rental and recreational paintball markers. Co2 tanks are filled by weight. Nitrogen (not nitrous that’s laughing gas) or high pressure air (HPA) works like a scuba tank on your gun, some of the newest tanks on the market can be filled to as much as 5000psi. All HPA tanks have some sort of regulator to bring the pressure down to what your gun can use. Since HPA is just compressed air and has no liqui
