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.
Q1: What materials can be selected for fire dampers?
A1: Standard material is galvanized steel plate; 304 stainless steel is optional for humid, corrosive environments. All material thickness can be customized.
Q2: What is the difference between manual, electric and fully automatic 70℃ fire dampers?
A1:
- Manual type: Only fusible link auto close at 70℃, needs on-site manual reset after fire.
- Electric type: 70℃ thermal shutoff + DC24V electric close, reset manually on site.
- Fully automatic type: Supports remote DC24V electric reset after fire, greatly saves post-disaster maintenance labor cost.

Q3: Can fire dampers also adjust airflow volume for daily ventilation?
A3: Yes. All our 70℃ fire dampers support multi-gear blade adjustment, which can work as air volume regulating dampers under normal non-fire conditions.
Q4: What temperature trigger standard for this series fire dampers?
A4: Standard trigger temperature is 70℃, which is widely adopted for air supply & return air ducts of ventilation and air conditioning systems.
Q5: Can dampers output feedback signal to fire control panel?
A5: All models are equipped with signal switch. Once the damper is fully closed, it sends feedback signal to the fire control center.
Q6: Can you produce non-standard custom sizes? What is the lead time?
A6: Yes, all dimensions can be customized. Regular sizes have stock; custom sizes normally take 5 working days for production.
Q7: How to install the fire damper? Any installation requirements?
A7: It shall be installed on ventilation ducts passing through fire partition walls/floors. We provide installation drawing for reference after order confirmation.
Q8: What power supply signal do electric actuators adopt?
A8: Standard control signal is DC24V, which is the universal specification for global fire alarm control systems.
Q9: What is the air leakage performance when the damper is fully closed?
A9: Built-in sealing spring strips, air leakage rate complies with international ventilation damper standard, excellent tightness for fire isolation.
Q10: Can we accept OEM order with customer brand logo?
A10: Yes, OEM service is available for bulk container orders. We can print customer logo on product frame and outer cartons as requested.
