The pressure regulator reduces the cylinder pressure from approximately 60 bar to a low working pressure of 2 bar, allowing for precise control of the CO2 supply. The regulator is screwed onto the CO2 gas cylinder, and the fine needle valve can be used to adjust the CO2 flow rate. It is compatible with CO2 disposable bottles (U-system) and refillable bottles (M-system). By unscrewing the knurled nut (W21.8x1/14) with an Allen key, the regulator can be fitted onto the M10x1 thread of the disposable bottles. The high-quality design is made from anodized aluminum, precisely CNC-machined in a titanium color. A reliable sealing washer replaces the O-ring. Delivery includes: 1 CO2 pressure regulator for refillable bottles, with a detachable adapter for compatibility with CO2 disposable bottles.
