The A.I.R. valve is an under rated valve in my opinion. A properly tuned A.I.R. valve can handle up to 16bps(without drop-off) provided there is a good air supply and the user doesn't short stroke. That's actually head-to-head if not better than a lot of high end marker valve systems. Pretty much any marker can fire over 20bps nowadays but the point they start to starve themselves of air is where accuracy(in theory) goes bad(in actuality, there's usually so little drop-off, the user doesn't realize it). However, since the A.I.R. valve is built on a mechanical marker system, these high rates of fire are extremely difficult to reach. I guess the A.I.R. valves potential lies in being a mechanical accomplishment rather than a practical one.

Although the A.I.R. valve performs best with a Compressed Air/Nitrogen system running it, it can also run off a Co2 system. When going this method, the more you do to keep liquid out of the valve, the better. Once liquid gets inside the actual valve, the valve will soon freeze and you'll just have to wait till it warms up again.

A.I.R. stands for Advanced Integrated Regulator. This means that no matter what your told, you dont need to buy an inline reg to lower the psi going into the valve. When running a Compressed Air tank, just hook the line up through a gas-thru foregrip or straight into the valve. The internal Reg. lowers the psi to about 450psi.
