Smoke Dampers: How They Support Safer Building Evacuations

SYDNEY - EntSun -- Installed within HVAC ductwork, smoke dampers restrict the movement of smoke during a fire. Connected to a smoke detection or fire alarm system, they close automatically and keep smoke near its source. This helps prevent its spread through ducts and plenums while preserving visibility and breathable air elsewhere.

Unlike fire dampers, which respond to heat, smoke dampers respond to smoke detection and work alongside smoke control systems. They are used in air conditioning, outside air and exhaust ducts, openings between smoke barriers, and pressurisation and smoke exhaust systems. They are found in hospitals, aged care, shopping centres, high-rises and public facilities, and are essential for compliance in many commercial, public and multi-storey buildings.

Similar to standard air control dampers, smoke dampers add a high-temperature rubber seal to all sealing surfaces to withstand the heat of the smoke they contain. Fire/smoke combination dampers offer dual protection.
