Avalanche Airbag Revolution: Fan/Battery Powered Airbag = Black Diamondโs โJetforceโ Black Diamond and Pieps have created a major revolution in avalanche airbag backpack technology by using a fan and battery in place of a compressed air cylinder. Their new system is called โJetforce.โ The Jetforce avalanche airbag backpack uses batteries and a fan to fill their airbag in place of a compressed air cylinder. Conventional avalanche airbag technology uses a compressed air cylinder to quickly deliver air into an airbag in your backpack once triggered by the user.
