Air Sources

A paintball gun needs something to shoot the ball, and CO2 (carbon dioxide) and compressed air both do it quite nicely. Learn the differences, the advantages and the disadvantages to each.

Should I use CO2 or Compressed Air?
The differences between CO2 and compressed air.

How does CO2 shoot a paintball?
Carbon Dioxide (CO2) is in a compressed, liquid state inside a CO2 tank. When it is released from the tank it expands into gaseous CO2 which propels the paintball out of the chamber.

What does ounce refer to with a CO2 tank?
Carbon Dioxide (CO2) tanks typically come in 9, 12, 16, and 20 ounce varieties. These numbers refer to how many weight ounces of liquid CO2 can fit in the tank.

What does an expansion chamber do?
An expansion chamber increases the amount of space the liquid CO2 has to expand in (and increases the area from which to pull heat), thus increasing consistency during intense firing.
