Multi-Compartment Multi-Blade Smoke Control Damper

The Multi-Compartment Multi-Blade Smoke Control Damper is a closure in smoke extraction duct devices. In the event of fire, the smoke and heat exhaust system opens the dampers in the affected section, thereby allowing the extract fans to remove the combustion products and heat from the areas at risk.

The damper is fire resistant and is designed for automatically or manually activated systems.

Smoke control dampers are intended for use in spaces comprising several fire compartments, which may be connected by a smoke extraction duct tested to EN 1366-8 or may be installed in the fire compartment construction.
