How Are Co2 Cartridges Filled?
CO2 cartridges are typically filled using a filling station or a hand pump. The filling station is a machine that connects to the cartridge and fills it with CO2 gas at high pressure. The hand pump is a manual device that requires physical effort to extract the CO2 gas from a larger tank and pump it into the cartridge. Once the cartridge is filled, it’s typically sealed off with a valve stem and can be used in various applications, including inflating bicycle tires, powering airsoft guns, and other similar applications.
