Description
Circular Smoke Control Damper SDE
The SDE is a motorised circular smoke damper that prevents fire and smoke from spreading in ventilation ducts. If the power in the motorised actuator is switched off by the system, the blade closes automatically (fail-safe closed). Circular Smoke Damper SDE is made of fireproof materials, with a non-combustible ceramic blade gasket. Once the damper has closed, the blade and sealing close the duct tightly, effectively preventing the spreading of fire and smoke.
