Fire Damper
It is a passive fire protection product designed to prevent the spread of fire and smoke through ductwork in a building.
The device typically consists of a metal frame and movable blades that are held open during normal operation.
When a fire occurs, a built-in thermal element (like a fusible link) melts at a specific high temperature, causing the blades to close and seal off the duct.
This action maintains the integrity of fire-rated walls and floors, compartmentalizing the fire to a localized area.
