Extendable CO2 pressure regulator (dual stage) for aquascaping

This premium regulator is just the best, dual stage, all-in-one, reliable and extendable for connecting several C2 atomisers or aquariums.

Dual stage regulators serve the same function as single stage regulators, but they ensure discharge pressure remains constant while the cylinder pressure decreases. Greater accuracy in pressure control is maintained because the pressure reduction is reached in two steps. Dual stage regulators are recommended for situations where a constant outlet pressure is required throughout the life of a gas cylinder.
