A high-quality and reliable professional pressure regulator from European production for supplying aquariums with CO₂. The AQUA-NOA professional pressure reducer is equipped with 2 pressure gauges on which the working pressure and cylinder pressure can be read. The cylinder pressure display indicates when the cylinder needs to be changed. The working pressure of this CO₂ pressure regulator can be easily and continuously adjusted, which is particularly important for diffusers that require a higher pressure. The integrated fine needle valve is used for fine adjustment of the CO₂ quantity and thus the number of bubbles.
We recommend a working pressure of 0.8 - 1.2 bar for standard CO₂ reactors and diffusers or bubble counters. A few devices with a higher back pressure, such as direct hose injectors or some non-return valves, require slightly more pressure, in which case you can set up to 2 bar. If the CO₂ supply can only be adjusted poorly and irregularly, please increase the working pressure carefully in 0.1 bar increments to remedy this problem until addition is possible continuously.
When changing the cylinder, please check the seal and replace it with a suitable spare part if necessary.
Modern design and sophisticated safety - European brand product with guaranteed spare parts supply.

Good pressure reducer and great service
I have already installed identical pressure reducers 3 times and am very satisfied with them. I can handle the hard seal in conjunction with an open-end spanner much better than the soft rubber seals, which I often overtighten and thus damage.
Today I couldn't get my old pressure reducer from another manufacturer to seal after changing the cylinder. Although the telephone times stated on the homepage were already over, I was able to reach Mr Kremser. After a short phone call, I had the new pressure reducer in my hands after 30 minutes. It has now been successfully installed. Many thanks for the prompt service on Saturday.

I am dissatisfied and Mr Dr was not particularly helpful when I contacted him by phone.
Compared to previous pressure reducers from DRAK, I have never been able to get this one tight, neither with soft nor hard seals.
Well-running customer tank two months after switching to DRAK
