Product Overview:
The Motorized Fire Damper (MFD) is a critical safety device designed to automatically shut off airflow in HVAC duct systems during a fire event. Equipped with an electric actuator, it ensures rapid closure upon signal reception from fire detection systems or Building Management Systems (BMS), helping to prevent the spread of fire and smoke through ductwork.
Our fire dampers comply with international fire safety standards and are available in both rectangular and circular shapes, with UL-rated or BS476-certified constructions.
