The Mammut RAS refillable cylinder is an essential component of the Snowpulse Avalanche Airbag. This cylinder can only be used with the Snowpulse Removable Airbag System and is not compatible with the older Snowpulse LifeBag Airbag System. The Refill Kit provides everything you need to prepare the cartridge for up to either 3 or 20 refills.

The Mammut Cartridge Refill Kit gives you three cartridges for your R. A. S. Refill the cartridges using a compressed air source (gasket and cover plate are required for each refill operation).
These Discs are required to refill an RAS cartridge and prepare it for another deployment. The RAS system has a mechanical trigger that punctures these discs to allow the airbag to fill.
