The pressure reducer is essential for reducing the pressure inside a CO2 bottle (approximately 50 - 60 bar/725 - 871.2 psi) to a pressure that allows for aquarium supply (0.1 - 2.5 bar/1.45 - 36.3 psi).

The CO2 pressure reducer from Sera Flor, equipped with an integrated fine adjustment valve, is made in Germany and reliably and safely reduces gas pressure. It can be connected to all common CO2 bottles equipped with an external valve.
