Description

This high-quality pressure regulator is used for regulating the pressure of approx. 54 bar inside the cylinder to a working pressure of approx. 1 to 3 bar. By combining the working pressure manometer and the cylinder pressure manometer you can regulate the CO₂ supply very precisely and you know at once when it is time to refill the cylinder. The integrated fine needle valve allows a very precise regulation of the CO₂ supply for the aquarium.

Please keep in mind that all components of the pressure reducer have been glued together by the manufacturer. These can not be unscrewed without damaging them. If the needle valve is removed, the manufacturer's liability will expire prematurely. The hose connection on the fine needle valve is an exception. This is not glued in due to the fine thread, so that in the event of a defect, it is not necessary to replace the entire fine needle valve but only the hose connection.

In addition to this pressure regulator, a version with double stage chambers is also available, which can be used in aquariums with particularly sensitive fish in order to completely prevent an increased CO₂ load: Hiwi Double Stage Pressure Regulator

The Hiwi pressure regulator is also available with a fixed solenoid valve (SV) for night shut-off and with a Ceck valve (CV): Hiwi Pressure regulator + SV & CV

Hiwi

Hiwi is a renowned German manufacturer of CO₂ pressure regulators. The highest level of quality and a long useful life are in their focus. These high quality standards do not exclude attractive prices, though.

Especially in aquascaping, the addition of CO₂ for the plants is something very basic, and thus it is really important to choose good CO₂ supplying equipment. Hiwi meets even the highest quality standards in every aspect und is thus the best choice when it comes to CO₂ pressure regulators.
