Cartridges for avalanche backpacks Arva 2018/2019
Fast airbag filling cartridges for avalanche backpacks contain compressed gas, which is released after manual activation of the system and fills the airbag(s) within three seconds. Most cartridges are disposable, but some can be refilled with compressed air. JetForce, Voltair and Alpride E1 systems do not need cartridges. For filling the airbags, they use a ventilator which fills the airbag with air.
