CONCOA 639 Series | Dome-Loaded Primary-Reserve Switchover | Panel-Mounted, Laser Assist Gas
The CONCOA 639 Series is a primary-reserve switchover supplying laser assist gas from two high pressure sources. It arrives pre-mounted on a stainless steel panel with flexible hoses for connection to bulk high pressure sources, and changes to the reserve bank when the primary is depleted.
The 639 is configured to order, so outlet range, gauges, connections and options are chosen when ordering: open ports or flexible pigtails at the inlet, with or without an Altos 2 remote alarm, and with or without an integral line regulator, which (or a downstream regulator) is needed where constant outlet pressure is required.
- Dome-loaded control for steady, high flow service
- Cartridge sensor for precise pressure control
- PTFE seats to 3000 PSIG or PCTFE to 4500 PSIG
- 1/4 in FNPT inlet and outlet, Cv 0.2
- 40-micron sintered bronze filter
- Weight 124 lbs (56 kg)
