COM-1 Series Crossover Manifold Regulator System
The COM-1 Series Cross Over Manifold was designed to allow the user to enjoy a virtually uninterruptible supply of regulated gas from bottles.
The COM-1 Series consists of two PR-1 Series (PR-2 optional) regulators mounted on a 300 series stainless steel bracket. The primary regulator, supplied with a tamper proof nut, is set to an outlet pressure approximately 15 psig higher than the secondary regulator, which is
supplied with a standard knob. 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. Once this occurs, the knob on the secondary regulator is rotated to a stop and the primary supply source can be safely changed while your process is still in operation.
The COM-1 series is supplied complete with 2″ diameter inlet pressure gauges for both regulators and a common outlet gauge.
