A true dual stage
Many CO2 pressure regulators on the market state that they are dual stage, but actually they are a single stage with a piston system or worse … not a dual stage at all.
The Pro Dual Stage CO2 pressure regulator from PlantedBox, however, is a full-fledged dual stage pressure regulator. This means that it has 2 internal diaphragms and springs that keep the working pressure 100% stable, even during an end-of-tank dump.
So you can be sure of the reliability of this system.
