Description
A Fire Rated Damper is a critical passive fire protection device installed within HVAC ductwork to prevent the spread of fire and smoke between fire-rated compartments. It is designed to automatically close when exposed to high temperatures, thereby sealing the duct opening and maintaining the fire resistance of walls, floors, and partitions.
Fire Rated Dampers are typically equipped with a fusible link or thermal sensor that activates when a preset temperature is reached. Once triggered, the damper blades close immediately, blocking the passage of flames and hot gases through the ventilation system. This function is essential in preventing fire from spreading rapidly through duct networks.
Manufactured from high-quality, heat-resistant materials such as galvanized steel or stainless steel, Fire Rated Dampers are built for durability and reliable performance. They are tested and certified to meet fire safety standards and are widely used in commercial, industrial, and residential buildings as part of comprehensive fire protection systems.
