Aquario Professional reducer is the highest quality product, created from start to finish especially for aquarium use. It is characterized by extraordinary CO2 dosing precision and a design that uses proven solutions. The reducer has built-in: bubble counter, precision valve, counter-valve and solenus valve, which are the most important components of the CO2 kit. Two clocks indicate the key parameters of the CO2 system: the pressure inside the cylinder and the operating pressure of the reducer. This makes it easy to predict the gas consumption of the cylinder and to read the level of pressure reduction. The reducer is made of metal alloy corresponding to the highest technical requirements, while guaranteeing high strength and reliability of its components. Thanks to this, the device ensures 100% tightness and high precision of gas dosing.
