Fire Dampers

Fire Dampers are designed to prevent fire, smoke and heat spreading through ductwork (used in HVAC systems and extraction systems) to other areas of the building.

They work when the normal temperature of the room rises to around 165 degrees Fahrenheit. This causes a fusible link attached to the damper actuator to melt closing the damper louvres. These links can be adapted for areas where the temperature is normally high.

Bell Lancaster engineers can inspect, clean and test fire dampers. It is recommended that this is undertaken at least annually following installation. On an initial visit the engineer will need to locate and access the fire dampers to complete a location list to enable effective future testing and inspection.
