The canister/cartridge is a metal cylinder that holds highly pressurized gas (normally in the range of 2,700 to 3,000 PSI), which is used to inflate the airbag(s). Currently, Mammut, BCA (Backcountry Access), ARVA, and WARY all offer user-refillable canisters. These can be refilled with compressed air at select ski shops, scuba or paintball shops, and some fire stations. ABS cartridges use compressed nitrogen and are not user-refillable; the empty cartridge is returned to a dealer to be refilled and the user receives a discount on a replacement full canister.
Newer airbag packs use battery operated fan systems to inflate the airbag and eliminate the need for cartridges. The airbag is inflated by a high speed fan, and can be deployed multiple times on a single charge (with exceptions). This system makes air travel with your airbag much easier and gives you the ability to practice inflation of your airbag at home or on snow knowing you have more than one activation.
** DISCLAIMER: TSA requires travelers on flights originating in the United States to demonstrate that gas cartridges are empty and not connected to the airbag. If you have an ABS airbag pack, you will also need to show that the activation handle is not live (there is an explosive charge in a live activation mechanism that punctures the cartridge). You will need to exchange the ABS activation handle along with the cartridge after deployment).
