Multi-compartment smoke extraction dampers are shutters in the smoke extraction ductwork systems.
The dampers are designed to remove heat and combustible products (e.g. smoke) from affected fire compartments.
In the event of fire the Smoke and Fire ventilation system opens the damper in the affected
section and removes combustion products and heat from this section.
The damper blade is controlled by an electrical actuating mechanism.
Dampers are fire resistant and are intended for systems with automatic activation.
Dampers can be installed in the construction of the fire compartment.
