Advantages of using HPA system in a GBB gun

The performance of an airsoft gun powered by conventional gas is very sensitive to the surrounding environment temperatures. Especially in sub-zero (sub 32 ºF) temperatures, it is practically impossible to use a GBB airsoft gun. The pressure of the propellant gas drops with the temperature and the gas condenses into a liquid state inside the magazine. When the gun is fired, the propellant liquid vaporizes back into its original gaseous state and further cools the gun.

Everything changes with the use of HPA. At similar low temperatures, compressed air stays in the gaseous form, therefore, practically no cooling of the gun occurs when firing. The compressed air pressure is also not so heavily affected by temperature. All you need to do is use the EPeS HPA adapter to connect your HPA system to your gun and happily fire back even when it is freezing cold.
