A high quality and reliable professional pressure regulators of European production for the supply of 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 display for the cylinder pressure indicates when the cylinder has to be changed. The working pressure of this CO₂ pressure reliever 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 bubble rate.

We recommend a working pressure of 0.8 - 1.2 bar for common CO₂ reactors and diffusers or bubble counters. Few devices with an increased back pressure such as direct hose injectors or some non-return valves need a little more pressure, then you can set up to 2 bar. If the CO₂ supply can only be adjusted poorly and irregularly, to remedy this problem please increase the working pressure carefully in 0.1 bar steps until the addition is possible steadily.

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 secure spare parts supply.

Review with rating of 1 out of 5 stars

bin unzufrieden und Herr Dr. war bei einer tel. Rücksprache auch nicht besonders hilfsbereit.

gegenüber früheren Druckminderen von DRAK habe ich diesen nie dicht bekommen. weder mit weichen noch harten Dichtungen.

Our feedback: Ich verwahre mich entschieden gegen den Vorwurf, nicht hilfsbereit zu sein. Das traf auch in diesem Fall nicht zu.In der mir vorliegenden Kommunikation (anderes als geschildert per E-Mail) wurden von meiner Seite eine Reihe von einfachen Lösungsvorschlägen für das Dichtigkeitsproblem aufgezählt sowie einige Punkte angesprochen, um abzuklären, ob ein Bedienfehler oder ein technischer Defekt vorliegt. Eine Überprüfung beim Hersteller wurde ebenfalls vorsorglich angeboten.Wenn sich ein Defekt heraus gestellt hätte, so hätte ich sicher eine befriedigende Lösung für den Kunden gefunden. Allerdings war die letzte Nachricht des Kunden dazu: „Damit haben Sie mein Problem gelöst, Vielen Dank !” Danach habe ich den Fall geschlossen und bis zur heutigen, aus meiner Sicht unzutreffenden Bewertung auch seit 20 Monaten nichts mehr dazu gehört.
Well-running customer tank two months after switching to DRAK
The tank, which is currently just under nine months old, was switched to DRAK almost two months ago. With the fertiliser combination KramerDrak Power and KramerDrak solution as well as good lighting, regular thinning is required.
