Description

The Wyin Aqua Mini Side Mount CO2 Regulator is a compact regulator for standard pressurised CO2 cylinders with a side-facing valve. Its W21.8 connection screws straight onto the valve's side outlet, so the regulator sits neatly beside the cylinder valve. That makes for a tidy setup in a cabinet or beside a nano tank.

Two gauges show cylinder pressure and working pressure, and the needle valve with its knurled knob sets your bubble rate. The bubble counter has a check valve built in to stop water running back towards the regulator, and your 4/6mm CO2 tubing pushes straight into the quick-plug outlet.

CO2 is switched by a 12V electromagnetic solenoid, powered by the included NZ/AU adapter. To run CO2 on the same schedule as your lights, plug the adapter into a plug-in timer.

Running a SodaStream cylinder, or one with an upright valve? The Wyin Aqua Mini Top Mount CO2 Regulator is built for those.
