Hiwi 2-stage double chamber CO2 pressure regulator for reusable bottles. High-quality and reliable pressure regulator from Hiwi. This pressure regulator has 2 pressure gauges, one for the bottle pressure and one for the working pressure. With the help of the adjustment wheel, you can easily adjust the desired working pressure. The Hiwi pressure regulator has a very precise fine needle valve, with which you can adjust the desired CO2 quantity. The advantage of a 2-step pressure reducer is that the bottle pressure can be kept constant. Another advantage for the 2-stage pressure regulator, compared to normal pressure regulators, is that at 20% CO2 residual quantity in the bottle, the working pressure would have to be continuously regulated manually, but the double chamber pressure reducer constantly holds the pressure until the bottle is empty. With a 10 kg bottle, however, approx. 2 kg which would normally last a whole while. For example, with a 2 kg bottle, 400 grams would be included. - Constant CO2 release until bottle emptying. - Pressure regulator for all standard aquarium CO2 reusable bottles (standard valve W 21.8 x 1/14 inches). - 2 pressure gauges for working and bottle pressure. - Precision fine needle valve for fine adjustment of the number of bubbles per basin. - Safety valve (relief valve). - Working pressure adjustment screw. - The working pressure and bottle pressure gauge offer you accurate control over the respective state of the individual values connection for standard 4/6 mm hoses. - Modern design and sophisticated safety. - German branded product with secure spare parts supply.
