Avalanche Airbags with gas blow fill their balloon(s) as gas flows under pressure from a cartridge into the balloon(s). After an inflation, the cartridge must be replaced. Sometimes you discard it (Alpride) or it is replaced based on a deposit system (all other brands), where you only pay for the refill.
