When working with pressurized gas systems, user safety is paramount. That is why JBL considers it a matter of course that the highest manufacturing standards are combined with precision. The CNC-milled pressure reducers ensure a precise fit. Internal flat seals ensure a long service life and robustness. Internal quality control of each batch ensures that any irregularities are detected before delivery and that these items can be blocked from further use. This makes them safe to use. Pressure reducers are sold on numerous online marketplaces that do not meet the requirements of aquatics and safe handling in long-term operation. This results in a short service life and frustration, which we would like to spare you. In addition to direct contact with the JBL team of experts via customer service, you are entitled to the extended 4-year warranty (JBL GarantiePlus) from JBL.
In line with the motto "better safe than sorry," some aquarium owners install several check valves in the same circuit. If you use the JBL PROFLORA direct inline diffuser or the JBL PROFLORA CO2 Count Safe bubble counter, for example, you already have an integrated check valve. If you use a separate check valve (JBL PROFLORA SafeStop) in addition, problems may arise when opening the check valves. This effect can be observed if the addition does not start again automatically after the night shut-off or interruption of the supply with the controller. Please note that, depending on the working pressure and the number of bubbles, it may take a few minutes between the start of the addition and the visible entry of CO2 into the aquarium. Each spring in a check valve requires a certain amount of pressure to open. Multiple springs can therefore interfere with each other and, depending on the distance between the two check valves, reduce the pressure on the spring to such an extent that it remains closed. Therefore, please always use only one check valve for your CO2 installation.
All check valves and backflow preventers from JBL require a working pressure of at least 0.6 bar for the valve to open. This feature is found in the JBL PROFLORA CO2 TAIFUN SAFESTOP, COUNTSAFE, and INLINE. The JBL PROFLORA TAIFUN diffusers also all work with this pressure. A higher working pressure is not necessary, which is why all accessories also work with the JBL PROFLORA BIO SETs (except JBL PROFLORA CO2 STARTER BIO SET). Depending on the installation, long hoses and other components may require a slightly higher working pressure than 0.6 bar, which is why the default setting of 1.2 bar is sufficient in all cases.
