C2X OB19.X1/25

This model is recommended for technical divers , CCR divers and Boats. The two-stage booster with its lower driving air consumption is particularly suited for professional use and for diving centers.

Examples of use

To fill a 3L tank from a storage tank with 100 BAR pressure, less than 50 seconds are requires to reach 220 BAR.
Even if used for longer period of time, the unique design of this booster prevents irs temperature from rising, thus allowing a safe filling procedure.
