Description

This high-quality pressure regulator by Hiwi is specially designed for use with Sodastream cylinders. No additional adapter is required. It is used to reduce the cylinder pressure to a working pressure of approx. 1 to 3 bar. By combining the working pressure gauge and the cylinder pressure gauge, the CO2 supply can be adjusted very precisely, and you can immediately see when it is time to replace the cylinder. The integrated fine needle valve allows very precise adjustment of the CO2 supply for the aquarium. The included bubble counter also enables visual monitoring of the CO2 dosage and helps to fine-tune the supply accurately. In addition, the integrated check valve protects the pressure regulator from backflow of water.

Please keep in mind that all components of the pressure regulator have been permanently bonded by the manufacturer. These can not be unscrewed without causing damage. If the needle valve is removed, the warranty will be void. The hose connection on the fine needle valve is an exception. Due to its fine thread, it is not bonded, so that in the event of a defect, it is not necessary to replace the entire fine needle valve, but only the hose connection.

Hiwi

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.

Hello! Which solenoid valve for night shut-off can you recommend for this?

You can use the Bavaria Fkuid Systems solenoid valve (https://www.aquasabi.de/Bavaria-Fluid-Systems-Magnetventil), which is then connected via a short piece of high-pressure tubing. Or you can use the pressure reducer with a pre-installed solenoid valve: https://www.aquasabi.de/Hiwi-Druckminderer-MV-RSV-Adapter-fuer-Sodastream-Zylinder
Translated from German
Hello, Hiwi has a pressure reducer with a permanently installed Sodastream connection. Is this the same one? Or is this the normal pressure reducer with an additional screw-on adapter so that it can also be used with normal CO2 cylinders?

The Sodastream adapter is built into this pressure reducer. If the pressure reducer is also meant to be used with a "normal" pressurized gas cylinder, you should choose this pressure reducer: https://www.aquasabi.de/Hiwi-Druckminderer The Sodastream adapter is available separately here: https://www.aquasabi.de/Hiwi-Adapter-Sodastream-W-218
Translated from German
Hi, is this pressure reducer also suitable for inline diffusers? Is the working pressure at least 3 bar? Kind regards Mark

The pressure reducer can be set to a working pressure of 3 bar. Using it with an inline diffuser is therefore possible in principle.

The pressure reducer is worth every cent. Before, I had a basic pressure reducer from JBL and only had problems.

Super Druckminderer, sehr zu empfehlen

Der Druckminderer ist jeden Cent wert. Ich hatte vorher einen einfachen Druckminderer von JBL und nur Probleme. Beim HIWI Druckminderer lassen sich die Blasen super einstellen. Man braucht keinen Adapter und das Teil ist von Anfang an dicht. Absolute Kaufempfehlung die einen Druckminderer für Sodastreamflaschen suchen. Man merkt wirklich die Qualität Made in Germany. Und ich unterstütze mit meinen Kauf lieber deutsche Firmen, als die Asiatischen.
