Sentinel CO2 Regulator

The Sentinel CO2 Regulator connects easily to 20- or 50-pound CO2 tanks to control the flow of CO2 with a precision flow gauge.  Its color-coded pressure gauge is easy to read and understand, and its120V solenoid is pre-wired with a six-foot power cord to connect to a controller or timer. When used with the Sentinel CO2 Regulator Expansion, more than one tank can be coupled together to extend the time between tank changes.
