POPULA Fire Damper & Air Volume Control Damper

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.

Product Classification & Core Introduction

70℃ Manual Fire Damper

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.

70℃ Electric Fire Damper

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.

70℃ Fully Automatic Fire Damper

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.

Air Volume Regulating Damper (Manual / Electric)

Used to balance airflow inside ventilation ducts, adjust air volume of each branch pipeline.

· Blade angle adjustable within 0~90°, multi-speed airflow control.

· Can be integrated with fire function to become combined fire & air regulating damper.

Main Product Features

Premium Thick Material Adopt thickened galvanized steel plate (stainless steel optional), anti-corrosion, resistant to deformation, stable long-term operation.

Low Air Leakage & Excellent Air Tightness Equipped with sealing spring sheets, air leakage rate meets national standard, tight sealing when fully closed.

Flexible Blade Movement Blades open and close smoothly without jamming, precise airflow adjustment.

Strong Pressure Bearing Capacity Stable structure, withstands high air pressure inside ventilation ducts.

Full Customization Service All dimensions can be tailor-made to match duct sizes for engineering projects.

Core Function in Building Fire Protection System

Smoke & Fire Isolation Quickly close in case of fire, block flame and high-temperature smoke spreading across fire compartments, restrict fire spread scope and reduce property loss.

Fire Alarm System Interlock Interlock with exhaust fans, air conditioning units. When damper closes, linked ventilation equipment stops automatically, avoiding fire risk.

Status Signal Feedback Send electrical feedback signal to fire control center after closing, allowing real-time system monitoring.

Evacuation Safety Guarantee Slow down smoke diffusion, gain precious time for personnel evacuation and fire rescue.

Application Scenarios

Office buildings, hotels, restaurants, auditoriums, cinemas, underground parking lots, hospitals, shopping malls, industrial workshops, warehouses and all commercial ventilation & fire-fighting duct projects.
