Sentinel Co2 Expansion Regulator

The CO2-EXP works with the CO2-REG. When used together, more than 1 tank can be coupled together to extend the time between tank changes.

The CO2-EXP CO2 expansion regulator assembly comes ready to install. Connect it to the CO2-REG, connect your second tank and you are ready to go.

• The CO2-EXP expansion Regulator connects to a second 20 lb or 50 lb CO2 tank.
  
  
• It is then joined together with the CO2-REG.
  
  
• The Precision flow-gauge on the CO2-REG releases between 1/2 and 15 SCFH of CO2 per hour (Standard Cubic Feet per Hour) from BOTH connected tanks.
  
  
• Multiple tanks can be connected, there is no limit!
