Pressure regulator for disposable CO2 cylinders • Precision pressure regulator, regulates cylinder pressure from 60 to 1.5 bar. The correct bubble count (amount of CO2) is then adjusted on the fine needle valve. • Preset working pressure (1.5 bar) means no need for complicated re-adjusting (adjustment possible, if required). • 2 pressure gauges display working pressure and cylinder pressure. • Can be converted to refillable cylinder system using adapter.
