I’ve been getting this question over and over again in the forums and other places. What is the difference between Co2 and HPA? Well, a big one. They’re two completely different elements. Co2 is carbon dioxide, a liquid or gas (depending on temperature). HPA, or High Pressure Air, is the element Nitrogen compressed. Did you know that when you take a breathe, about 95% of what you’re inhaling is nitrogen, the same kind you shoot from your paintball gun? Did you really pay attention in Bio or Chemistry class?
Anywho, the difference is huge as far as how it performs on your paintball gun/marker. It’d be a good idea to educate yourself about the topic in order to keep your gun in tip-top shape.
Bone up and read Co2 vs HPA.
Blessings to you.
