Never lose CO2 during a rush — Carbo-Switch™ senses and switches CO2 tanks automatically. Carbo-Switch™ 2100: When the customer’s supply regulator is attached to the output fitting of the Carbo-Switch™, it will read the pressure of Tank 1, while the gauge on the right side of the unit will read the pressure of Tank 2. The Carbo-Switch™ first draws gas from Tank 1. At this point, the output from the Carbo-Switch™ unit is equal to the regulator setting of Tank 1. When the pressure of Tank 1 drops to 200 psi, the Carbo-Switch™ begins drawing gas from Tank 2. As soon as Tank 1 is replaced, the Carbo-Switch™ begins drawing from Tank 1 again. Should the pressure of Tank 2 drop below 200 psi before Tank 1 is replaced, the Carbo-Switch™ will draw from both cylinders equally until both are empty, or one or more of the cylinders are replenished. The Carbo-Switch™ is pressure operated and has no moving mechanical or electrical parts to fail.

Carbo-Switch™ 3100: Carbo-Switch™ 3100 is a three-cylinder Automatic Switchover Manifold with same operating principle as the two-cylinder Carbo-Switch™ manifold except there are two cylinders on the primary supply side and one cylinder as the back-up gas source Carbo-Switch™5100: Carbo-Switch 5100 is a Five-Cylinder Automatic Switchover Manifold that operates the same as the two-cylinder Carbo-Switch™ manifold except there are four cylinders on the primary supply side and one cylinder for the back-up gas reserve.
