Fire Damper

What are Fire dampers?

A fire damper is a mechanical device, which is operated either manually or automatically, to prevent the fire or smoke from spreading through a ductwork system. Fire dampers are located in the ductwork where it passes through fire retardant walls or floors.

How do the Fire Dampers work?

In most cases a fire damper is held in the open position with a fusible link that melts at 72°C, releasing the blades of the damper to close and stop the fire from spreading through the ductwork.

Fire Dampers inspection

Fire Dampers are a critical part of the fire protection system. Correctly operating fire dampers can make a significant difference in the case of fire. If they fail to close they won’t prevent fire from spreading and that could lead to destruction and death.

It is very important to make sure that the fire damper works properly when fire occurs. Drop testing, cleaning and maintenance of fire dampers is crucial to keep your fire safety system in good condition.
