The HP system is the combination of HP bottle and regulator. br>(engl. High Pressure - short HP) Also called compressed air, is highly compressed air with a pressure of 200 bar or 300 bar.
In order to use them, the pressure upstream of the marker is reduced to a usable working pressure of approx. 35 bar to 55 bar by means of HP regulators. Unlike CO2, HP pressure is not temperature dependent.
