Product Specification
| High Light | Customizable Sizes Fire Damper ，Air Volume Control Damper For HVAC | ||
Fire dampers and air volume regulating dampers are essential safety and air adjustment fittings for building HVAC ventilation and fire protection duct systems. Manufactured in Foshan, Guangdong, available in galvanized steel or stainless steel materials, all sizes customizable.
Model: FHF WS-FK/70℃C
· Normally open; automatically closes when ambient temperature reaches 70℃ via fusible link.
· Manual open & close operation, 5-speed airflow adjustment, can be used as air volume damper in daily ventilation.
· Output position feedback signal upon closing, supports interlock with exhaust fans.
Model: FHF WSDc-FK/70℃C
· Normally open; fusible link auto shutoff at 70℃, also supports DC24V electric closing.
· Manual operation available, multi-gear airflow regulation.
· Signal feedback after closing, realizes interlinked shutdown of ventilation equipment.
Model: FHF WSDj-FK/70℃C
· Normally open; fusible link shutoff at 70℃ and DC24V electric closing.
· Unique advantage: Can be electrically reset remotely after fire, no need on-site manual reset.
· Supports fan interlock, remote control, closed-loop fire system management.
Used to balance airflow inside ventilation ducts, adjust air volume of each branch pipeline.
· Blade angle adjustable within 0~90°, multi-speed airflow control.
