Co2 Tanks

What is the difference between compressed air and CO₂?

                When considering a gas source for your paintball marker, there are two types to choose from: compressed air and CO₂. CO₂ is the most widely used gas for paintball markers. CO₂ tanks are cheaper than compressed air tanks and are available in a variety of sizes from 4 to 24 ounces. Many sports supply stores and most all paintball fields are capable of filling CO₂ tanks and generally charge by the ounce to fill them. Compressed air tanks are more expensive than CO₂ tanks and can only be filled by fields and paintball specific shops. They do however provide a significant performance increase for your paintball marker. Compressed air provides a more consistent gas source and will not freeze internal seals like CO₂ under higher rates of fire.

Which should I purchase?

            There are a few main points to consider when choosing between compressed air and CO₂. One of the most important factors to consider is the type of marker you will be using. Higher-end brands such as DLX, Dye, Eclipse, Bob Long, DP, and Empire strongly recommend compressed air as a gas source for their electronic markers. These markers many times are not compatible with CO₂ and can be damaged if CO₂ is used resulting in expensive repairs. Mechanical, blowback and most milsim style markers from companies such as BT, Tippmann, and GOG are capable of using CO2 or compressed air as a gas source.

                The second factor to consider is the availability of a certified fill center. CO₂ is more widely available than compressed air in most locations. If you frequently play paintball at an established field, many times it is cheaper in the long run to purchase a compressed air tank, as fills are usually free. If you play paintball in the woods with your friends and are far from an established field, CO₂ is recommended as a gas source.
