Is 1.2 bar working pressure sufficient for my CO2 system?
For a long time JBL CO2 pressure reducers had a preset working pressure of 1.5 bar. This has become established in people's minds. With the new JBL PROFLORA CO2 pressure reducers with pressure gauges, the working pressure is set to 0 bar on delivery. You admit CO2 via the large adjustment knob for the working pressure and turn it until the desired working pressure is reached. Approx. 1.2 bar is the maximum setting here. A minimum of 0.6 bar is required for the operation of all JBL non-return valves or backflow protections. This ensures that the check valve opens. A higher working pressure is not necessary, which is why all the accessories also work with the JBL PROFLORA BIO SETs. A lot of CO2 accessories available on the market give very different specifications for the working pressure. To be on the safe side, the standard of 1.5 bar which is common on the market is mentioned. As a rule, the working pressure required is the same as that on which the JBL PROFLORA CO2 accessories are based. Only a few exceptions require a working pressure of over 2 bar and are very special technical components.
