Aluminum air tank with inflator head and a volume of 1 liter, which can be inflated with any standard floor pump up to 200 psi / 14 bar for quick and particularly easy filling and sealing of tubeless tires. Once the mode selection lever is switched from "Charge" to "Inflate," compressed air flows from the air tank into the tire, allowing the air pressure to be perfectly adjusted with the connected floor pump. The integrated and flexible hose with pump head is compatible with Presta and Schrader valves and relieves the valve stem during use.
