The Aqua-Noa CO2 Pressure Regulator Basic E2 is a pressure regulator with two gauges and is suitable for disposable bottles. A CO2 pressure regulator is always necessary to reduce the cylinder pressure (50-60 bar) to a working pressure suitable for the aquarium (2 bar). One gauge is used to read the cylinder pressure, while the other gauge is used to read the working pressure of the CO2 system. The regulator itself is not adjustable and is fixed at approximately 2 bar.
Using the built-in needle valve, the CO2 supply can be perfectly adjusted.
