Order LookupFire & Smoke Dampers
Fire and smoke dampers automatically close when temperatures reach a certain point to prevent the spread of smoke and fire through the duct system. They use a fusible link that melts above a specific temperature, releasing a spring-loaded damper or blade that blocks smoke and fire from moving through the duct.
Rectangular Motorized Smoke Dampers
Rectangular motorized smoke dampers close and seal HVAC ducts when their power supply is interrupted. These units feature an electric actuator that holds the damper open when electrical power is connected. This actuator swings closed automatically when it loses power and blocks the spread of smoke through the ducts.
Dynamic
Dynamic dampers will close in the event of a fire, even if the HVAC system is operating. They feature mechanisms that are strong enough to close the damper and stay closed, even with the blower running at full speed.

Rectangular Motorized Fire & Smoke Dampers
Rectangular motorized fire and smoke dampers have a fusible link and electric actuator that automatically close the damper when power is lost or the temperature exceeds the trigger point. These dampers eliminate the spread of smoke and flames in HVAC systems.

Round Motorized Smoke Dampers
Round motorized smoke dampers connect to round HVAC ducts and seal them when their power supply is interrupted. These dampers feature an electric actuator that holds the damper open when electrical power is connected. This actuator swings closed automatically when it loses power and blocks the spread of smoke through the HVAC system.
