Fire dampers are installed in ventilation or air conditioning (HVAC) ducts to prevent fire from spreading inside the ductwork. Quanda provides a variety of fire dampers made of a variety of material to make them suitable for different applications. Materials include galvanized sheets, cold plates (A3) or stainless steel (which is ideal for clean room air conditioning systems and kitchen exhaust systems).

Features

The damper blades on the fire damper remain open in normal conditions. If the air temperature within the damper duct exceeds 70℃/150℃, the fusible link will melt and close the fire damper.
After the fusible link has melted, the fire damper remains closed until it is manually reopened.
It will regulate the airflow from 0°to 90°
The fire damper will output a signal to confirm the fully closed position. This function can be turned on and off according to your requirements.

FHF-W Fire Damper

Features
1. This fire damper remains open in normal conditions. If the air temperature inside the damper duct exceeds 70℃/150℃, the fusible link will melt to close the fire damper.
2. The fire damper is made of different materials to meet different application needs, including galvanized sheets, cold plates (A3) or stainless steel (which is ideal for clean-room air conditioning systems and kitchen exhaust systems).
FHF-WS-FK Fire Damper

Features
1. This fire damper remains open in normal conditions. If the air temperature inside the damper duct exceeds 70℃/150℃, the fusible link will melt to close the fire damper.
2. After the fusible link has melted, the fire damper remains closed until it is manually reopened.
3. It will regulate the airflow from 0 to 90° in five stages.
4. The fire damper will output a signal to confirm the fully closed position. This function can be turned off according to customer requirements.
5. It is made using a galvanized sheet.
FHF-W-K Fire Damper

Features
1. This fire damper remains open in normal conditions. If the air temperature inside the damper duct exceeds 70℃/150℃, the fusible link will melt to close the fire damper.
2. After the fusible link has melted, the fire damper remains closed until it is manually reopened.
3. The fire damper is made of different materials to meet different application needs, including galvanized sheets, cold plates (A3) or stainless steel (which is ideal for clean-room air conditioning systems and kitchen exhaust systems).
FHF-WSDc-K Fire Damper

Features
1. The fire damper remains open in normal conditions. If the air temperature within the damper duct exceeds 70℃, the fusible link will melt to close the fire damper. This fire damper is also capable of being closed manually.
2. After the fusible link has melted, the fire damper remains closed until it is manually reopened.
3. The fire damper will output a signal to confirm the fully closed position.
FHF-WSDc-FK Fire Damper

Features
1. This fire damper remains open in normal conditions. If the air temperature inside the damper duct exceeds 70℃/150℃, the fusible link will melt to close the fire damper.
2. The fire damper is made of different materials to meet different application needs, including galvanized sheets, cold plates (A3) or stainless steel (which is ideal for clean-room air conditioning systems and kitchen exhaust systems).
FHFK-W Fire Damper

Features
1. The fire damper is equipped with single-layer adjustable aluminum louvers to regulate airflow direction.
2. The louvers remain open in normal conditions. If the temperature within the damper duct exceeds 70℃, the memory alloy will act on the fusible link to close the fire damper.
FHF-WSDc-K Fire Damper

Features
1. The fire damper remains open in normal conditions. If the air temperature within the damper duct exceeds 70℃, the fusible link will melt to close the fire damper.
2. After the fusible link has melted, the fire damper remains closed until it is manually reopened.
3. This fire damper is closable using an electric driven 24V DC power supply. It can also be manually closed.
FHF-WSDcDj-K Automatic Fire Damper

Features
1. The fire damper remains open in normal conditions. If the air temperature inside the damper duct exceeds 70℃, the fusible link will melt to close the fire damper.
2. It can be closed and reopened via an electrically driven 24V DC power supply.
3. The fire damper will output a signal to confirm the fully closed position. It is also capable of working in conjunction with other equipment.
PFHF-WSDc-K Smoke and Fire Damper

Features
1. The fire damper remains open in normal conditions. If the air temperature within the damper duct exceeds 280℃, the fusible link will melt in order to close the fire damper.
2. After the fusible link has melted, the fire damper remains closed until it is manually reopened.
