Specifications
Smoke extraction dampers - multi are shutters in the smoke exhaust piping systems. The dampers are designed to remove heat and combustible products (e.g. smoke) from effected 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 electrical actuating mechanism. Dampers are fire resistant and are intended for systems with manual or automatic activation. Dampers are designed for using in fire compartments that can be connected to the smoke exhaust ducts (tested according to EN 1366-8) or they can be installed in or on the construction of the fire compartment. Dampers can be delivered with or without flanges.
