Combination Fire Smoke Damper

Combination Fire Smoke Damper is an integrated smoke control and exhaust damper with modular combination design. It consists of independent fire protection functional units and smoke exhaust functional units, and can be selected for integrated installation or split installation according to pipeline layout, meeting the dual protection needs of ventilation fire protection and high-temperature smoke exhaust at the same time. Both units remain normally open under daily conditions, taking into account system ventilation and smoke exhaust standby. In the early stage of fire, when the flue gas temperature reaches 70℃, the fire protection unit triggers first to block the initial spread of fire. When the temperature of smoke exhaust pipeline rises to 280℃, the smoke exhaust unit automatically triggers to close, protecting rear-end smoke exhaust equipment and forming a two-stage protection combined smoke control and exhaust system.

Our Combination Fire Smoke Damper adopts a modular design concept. The fire protection unit and smoke exhaust unit can be used in combination or installed separately at different pipeline nodes, with extremely strong adaptability. Both valve bodies are made of high-quality galvanized steel sheet, equipped with independent temperature-sensitive triggering mechanisms and signal feedback devices, which can be respectively connected to fire control systems to realize independent status feedback and linkage control. With 23 years of R&D and manufacturing experience in smoke control and exhaust equipment, our Combination Fire Smoke Damper effectively solves the problems of cumbersome multi-valve arrangement and complex system in complex pipeline systems. It can simplify system design, reduce installation workload, and is especially suitable for smoke control and exhaust systems of large complex buildings.

• Large buildings: Complex smoke control and exhaust systems in commercial complexes, airport terminals, high-speed railway stations, etc.
• Underground spaces: Scenarios with both fire protection and smoke exhaust requirements such as underground garages, underground shopping malls, and urban pipe galleries
• Industrial buildings: Comprehensive smoke control and exhaust systems in large workshops and warehousing logistics centers
