JBL PROFLORA CO2 REGULATOR PROFESSIONALPressure regulator with 2 pressure guages and solenoid valve for night switch-off for CO2 aquarium plant fertiliser systems The pressure reducer reduces the cylinder pressure from approx. 60 bar (displayed on pressure gauge 1) to a low 1.2 bar working pressure (displayed on pressure gauge 2), so that the CO2 supply can be easily regulated Screw the pressure reducer onto the CO2 pressurised gas cylinder, connect the solenoid valve to the timer (not included) or CO2 control unit (not included) and regulate the amount of CO2 added using the fine needle valve The pressure reducer fits disposable CO2 cylinders (U system) and refillable cylinders (M system). By unscrewing the knurled nut (W21.8x1/14) with an Allen key, the pressure reducer fits the M10x1 thread of the disposable cylinders Very high-quality design: anodised aluminium, precisely CNC-milled in titanium colour, low-noise solenoid valve. Reliable sealing washer instead of O-ring Package contents: 1 CO2 pressure reducer with 2 pressure gauges (for working & cylinder pressure) for disposable and refillable cylinders, solenoid valve and unscrewable adapter - then suitable for disposable CO2 cylinders
