Autochangeover panel

Description:

P3400 Series Automatic Specialty Gas Control Panel

Gentec P3400 Series Specialty Gas Control Panel is a dual bank semi-automatic changeover system, providing a continuous gas supply without interrupting the system during cylinder(s) replacement. When the primary bank is nearly depleted, a changeover will occur, in which the reserve bank will begin to supply gas to the system. The inlet valve on each bank provides the user additional safety while replacing the cylinder(s) on the empty bank before the next changeover occurs. Available in both stainless steel and brass. This gas switchover is ideal for high purity gas applications as high pressure gas purging function is incorporated into its design.
