Description
When Inert Gas and Carbon Dioxide fire suppression systems are discharged, the agent entering the enclosure results in a positive pressure and displaces the air from the room. Suitable means of pressure relief/venting should be used in order to avoid structural damage to the building and equipment.
PV Pressure Vents have been developed to provide this pressure relief venting. The pressure vent blades start to open at above 55 to 60 Pa and are fully open at 100 Pa. The special design provides 90% free vent area from 100 Pa room pressure. This means that fewer vents are required, reducing the number of holes that must be cut in enclosure walls, which minimizes installation costs.
