The duration a full HPA (High-Pressure Air) tank lasts depends on its size (measured in cubic inches) and pressure (usually 3000 or 4500 PSI), as well as how quickly you use air (your rate of fire). On average, a standard HK Army 68/4500 tank can provide around 1000-1500 shots before needing a refill. Smaller tanks, such as the HK Army 36/3000 tank can provide approximately 500 shots depending on your PSI (pound per square inch) on your regulator.
