HIGH-X PRESSURE RELIEF DAMPER

RESOURCES

The High-X Range of Pressure Relief Venting system uses a patented design that is unique in the world of pressure relief venting for gaseous extinguishing systems.

The system provides a greater efficiency factor of free vent area at all pressures. This means that you need less PRD vents, smaller holes, less builders work and reduced system costs.

The High - X PRD's are unique because they can be mounted in a wall or ceiling (horizontal or vertical ). We also have door and duck mounted unites available. This leads to a much greater range of pressure relief systems than ever before.
