Fire damper MSD

MSD – Multi compartment smoke extraction damper allows usage in smoke extraction ducting systems. Characteristics - Square dampers from 160 × 180 mm to 1500 x 800 mm - Round dampers from ø 160 to 630 mm - CE certified acc. to EN 12101-8 - Tested in accordance with EN 1366-10 - Classified acc. to EN 13501-4+A1 as - EIS 120, actuating AA for multi Fire Compartment - External Casig leakage class C, Internal leakage class 2 acc. to EN 1751 - Cycling test in class C 10 000 acc. to EN 15650 - Damper actuating by electrical actuator - Max. air speed in the system of 15 m/s, allowed pressure up to 500 Pa, or underpressure up to -1500 Pa 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
