Semi-Automatic Switchover Manifolds

GENTEC® 210 / B220 series semi-automatic system is designed for a continuous supply of high purity gases. It consists of a primary bank and a reserve bank of cylinders. Because of the differential pressure between the primary and reserve banks, the changeover takes place automatically when the primary bank is depleted to provide a continuous supply of gas from the reserve bank. However, in order to activate the next switchover, the regulators on both banks need to be readjusted upon changing the cylinders using the arrow indicator. Stable pressure output is provided by the second pressure regulator on the main line.
