Ruidong fire dampers include two types: 70°C fire damper and 280°C smoke exhaust fire damper. The 70°C fire damper is typically installed at the outlet of air conditioning and ventilation equipment, remaining in an open position under normal conditions. In the event of a fire, when the temperature reaches 70°C, the valve automatically closes, effectively preventing the spread of fire and smoke. The 280°C smoke exhaust fire damper, on the other hand, is installed on smoke exhaust ducts and remains open. It closes when the temperature reaches 280°C, preventing the fire from spreading to other fire zones and areas. It is generally installed at the exhaust fan outlet and smoke exhaust zone isolation points.

Ruidong fire dampers are available in square and round shapes, with sizes customizable to meet customer needs and adapt to different installation environments and duct sizes. The damper frame is formed by roll forming and riveted using Tox equipment, preventing damage to the galvanized layer and ensuring excellent corrosion resistance. The blades are also formed by die stamping, providing a smooth, flat, and deformation-resistant surface. The blades and frame are sealed with stainless steel spring seals, offering excellent sealing performance.
Ruidong fire dampers use square shafts and brass shaft sleeves, providing smooth rotation and wear resistance, significantly extending their service life.
