Gas Suppression

Pressure Relief Dampers

Pressure Relief

Pressure venting is an essential adjunct to many types of gaseous fire protection systems, but incorrectly designed venting can have serious consequences.

Solarfire Systems calculate the size of the damper required at the design phase of your project and will source and supply the most suitable pressure relief damper for the project.

Pressure Relief is required to protect the structural stability of a room or enclosure.

Pressure relief dampers remain closed under normal conditions but, upon a gas discharge, they open to relieve both negative and excess positive pressure and protect the integrity of the room. Once the pressure of the room normalises, they close again to maintain the integrity of the room.

Where the damper is fitted to an external wall, anti-intrusion bars or weatherproof louvres will be fitted.
