Multi Smoke Extraction Damper for Smoke Ventilation Systems
SEDM
Multi Smoke Extraction Damper SEDM
The multi smoke extraction damper SEDM is a shutter designed for installation in smoke exhaust piping systems. Its primary function is the effective removal of smoke, combustion products, and heat from affected fire compartments. In the event of a fire, the damper opens in the relevant section, allowing for the evacuation of harmful substances. Control is managed by an electrical actuating mechanism, with options for manual or automatic activation.
