Me CO2 Regulator Basic – CO2 Pressure Regulator with Two Gauges and Fine-Adjustment Valve

The Me CO2 Regulator Basic is a single-chamber CO2 pressure regulator for refillable bottles with a W21.8 connection. It has two gauges for bottle and working pressure, a fine-adjustment valve and a robust metal housing.

For a first pressurised CO2 system you don't need a solenoid or smart features, just a reliable way to feed a steady amount of CO2 to your plants. The Basic does exactly that. If you want CO2 to switch off at night on a timer, choose the Me CO2 Regulator Ultra with built-in solenoid valve.

Frequently asked questions

Does it have a solenoid valve?
No. CO2 runs continuously. For night switch-off on a timer, choose the Me CO2 Regulator Ultra.

Single-chamber or double-chamber – what's the difference?
In a single-chamber regulator the working pressure can change slightly as the bottle runs low, so check the bubble rate when the bottle is nearly empty. Double-chamber regulators keep it constant until the end.

Does it fit disposable CO2 cartridges?
No, it is made for refillable bottles with a W21.8 connection.
