Control Damper Fire Damper Product Description: Control Damper is used to regulate airflow within HVAC systems for precise ventilation control. It can be manually or automatically operated, allowing integration with building management systems (BMS). Designed for durability and efficiency, it ensures optimal air distribution and energy savings. Specification: The Control Damper is constructed from high-strength galvanized or stainless steel for corrosion resistance and long-term durability. Blade types include airfoil or flat blades, with parallel or opposed blade operation, depending on airflow requirements. It is available in various sizes and configurations, suitable for low to high-pressure systems. The damper can be equipped with electric or pneumatic actuators, and offers options for leakage class ratings, low-pressure drop, and seamless integration with HVAC automation systems. Product Description: This damper is activated by heat during a fire event. When the temperature rises and reaches the melting point of the fusible link (UL Listed 165°F), the damper blade drops like a curtain due to the force of a stainless steel spring and the blade’s self-weight. This design enables rapid fire compartmentalization in air duct systems. The damper is tested and certified in accordance with UL 555, the standard for fire dampers, which evaluates closure reliability, operation during elevated temperatures, dynamic airflow conditions, up to 3 hours of fire resistance. The FD-EL series provides dependable protection in both static and dynamic systems. Specification: The FD-EL and SD-EL series dampers are UL 555 and UL 555S certified, with 3-hour fire resistance and low smoke leakage performance. Frames and blades are made of galvanized or stainless steel, and are closed using a stainless steel spring and gravity drop. FD-EL uses a 165°F UL-listed fusible link, and SD-EL includes an electric thermal link activated by smoke or heat. Installation is possible both horizontally and vertically, and smoke dampers include a manual reset handle. All models comply with NFPA 90A, 80, and 105 standards.
