Engineered for passive fire protection and life safety, our fire dampers prevent the spread of flames across fire-rated barriers by mounting directly within ductwork at penetration points. Each unit is constructed from a robust 1.5 mm galvanized steel frame and blades paired with durable brass bushings to ensure long-term, frictionless operation. Designed for versatile protection, the damper automatically seals off air ducts when high heat activates its thermal release device, or operates via an integrated electric actuator in motorized models for automated building management and alarm system response.
