620 Series Switchover

Pressure differential automatic switchovers for carbon dioxide laser resonator gases
6203008-01-000 shown

The 620 Series Switchover is an automatic system designed to provide a continuous supply of laser purity gas. The system comes with either flexible hoses for use with two cylinders (one per side), or manifolds for two or more cylinders per side. CONCOA 620 Series Laser Gas Switchovers require final pressure regulation, which may be ordered integrally to the system, or separately for installation at the point-of-use.

Note: This item has been discontinued. Please see the CONCOA 526 Series Automatic Switchover for all applications previously using the 620 Series Automatic Switchover.
