COM-2P Series
Cross Over Manifold

COM-2P Series Cross Over Manifold

The COM-2P Series Cross Over Manifold is the next logical step in engineering evolution from the COM-1. This unit was designed to allow the user to enjoy a virtually uninterruptible supply of regulated gas with only a 0.01% change in outlet pressure with varying inlet pressure from bottles. Borrowing from the technology of the time proven CYL-20 Series cylinder regulators, the COM-2P employs two discrete single stage

regulators built into a single body. These regulators serve as the primary and secondary changeover regulators with the common outlet port connected to a single PR-1 Series regulator.

As the primary supply source depletes and falls below the operating outlet pressure of the primary regulator, the secondary supply source takes over, feeding through the secondary regulator to the PR-1 Series regulator. Once this occurs, the knob on the secondary regulator is rotated to a stop and the depleted supply source can be safely changed while your process is still in operation.

The COM-2P series is supplied complete with 2″ diameter inlet pressure gauges for both regulators, a common outlet gauge and process shut off valves. All of this comes mounted in an attractive 300 series stainless steel panel that has informational labels permanently silk screened on the face identifying ports and gauges. This panel is easily surface mounted near the gas supply.
