Circular damper doors are commonly used equipment in the air supply system. Electric circular dampers consist of an electric actuator and a damper. The adjustable electric circular damper can regulate the opening degree of the damper to control the size of the air volume. The two-way electric circular damper serves for closing and opening functions.
Circular damper doors are primarily used for regulating boiler hot air ducts, available in 18 sizes ranging from DN100 to DN1400. The leakage rate of round dampers in the fully closed position is ≤3%; working pressure ≤50kpa; working temperature ≤400°C.
