This fire smoke exhaust fire damper is a core supporting component for building fire smoke control systems, equipped with a standard 280℃ thermal fuse actuator and installed inside smoke exhaust ducts.

It remains normally closed under normal conditions. In case of fire, it opens automatically upon receiving fire control signals to discharge indoor smoke outdoors. When flue gas temperature inside the duct rises to 280℃, the thermal fuse melts under heat, and the damper closes instantly to block the duct, preventing fire and high-temperature smoke from spreading through pipelines across floors and zones. It is widely applied in mechanical smoke exhaust fire protection projects of high-rise apartments, commercial complexes, underground parking lots, industrial workshops and other buildings.

The valve body is integrally stamped from thickened hot-dip galvanized steel plate; anti-corrosion stainless steel version is available for customization. It is fitted with certified fire actuators from professional manufacturers featuring precise temperature detection and stable operation. The valve blades open and close smoothly without jamming and achieve tight sealing when shut. The sturdy structure resists impact and wind pressure deformation, with anti-rust surface treatment for long service life.

As a direct manufacturer, we provide customized rectangular and round dampers in all sizes. With years of production experience, all products undergo full inspection before delivery for stable pressure resistance and smooth operation. Professional installation guidance and comprehensive after-sales service are provided.
