Specifications
Multi smoke dampers are shutters in the smoke exhaust duct 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 automatic activation. Dampers can be installed in construction of the fire compartment.Basic types of dampers:MSD Cycling test with load (possible design .44, .54)MSD-W Cycling test without load (possible design .44, .54, .4M0, .4M1, .5M0 and .5M1)Dampers MSD can be open against flow and pressure.Dampers MSD-W has to be open with the help of flow or without flow present.
