Motorised Fire Dampers


4 Hours Fire integrity rating


The Blendair Motorised Fire Damper Series MFD is a HEAVY DUTY damper, designed to provide efficient airflow control and to impede the spread of fire and/or combustible products (e.g. smoke) through wall openings to other fire compartments of an air-handling system.

This range of Motorised Fire Dampers finds its application in building construction and mining industry where ventilation, heating, cooling or air-conditioning systems are employed.

The design concept is based on an interlinked set of blades connected with a solid drive shaft using a standard pneumatic actuator or electric –electronic fail-safe spring return actuator with a fusible link incorporated into the closing mechanism and spring clip holding the blades in the closed position after closure.
