CO2 Cartdriges 

Carbon dioxide (CO2) has the following characteristics and operation in cylinders for air pressure rifles:

• It is non-flammable and chemically stable and inert under atmospheric conditions

• It can dissolve in water to form carbonic acid, which has corrosive effects on steel and some metals

In CO2 cylinders for rifles:

• Carbon dioxide is mixed with a small amount of oil and pressurized in liquid form

• The evaporation of the liquid CO2 cools the cylinder very quickly, similar to a CO2 fire extinguisher

Operation in CO2 pistols and revolvers:

• CO2 is used as the pressure source

• Inside the pressurized container, some of the CO2 turns into liquid, coexisting with the gas

• When the trigger is pulled, a valve opens inside the cylinder, allowing gas to flow into the barrel

• This sudden drop in pressure creates an explosion that fires the projectile at high speed

• Almost instantly, more liquid turns into gas to replace the released gas, preparing the cylinder for the next shot
