Key features

Galvanized Steel Construction-Made of high-quality galvanized steel sheet, offering good corrosion resistance, durability and mechanical strength for HVAC and ventilation duct systems.

Automatic Thermal Activation-Equipped with a temperature-sensitive fusible device. When the duct temperature reaches the rated activation temperature, the fusible link releases and the damper blades

Good Blade Sealing Performance The multi-blade structure is designed for close blade contact when closed, helping reduce unwanted air leakage through the damper.

Airtightness Tested-The damper undergoes airtightness testing to help ensure stable sealing performance and reliable operation in HVAC duct systems.

Customizable Dimensions-Available in customized rectangular or square dimensions according to air duct size, installation space and project requirements.

Durable and Corrosion Resistant-The galvanized steel construction provides resistance to corrosion and is suitable for long-term use in commercial and industrial ventilation environments.

Easy HVAC Duct Installation-Designed for duct-mounted installation and suitable for integration into air conditioning, ventilation and fire protection systems.

Wide Range of Applications-Suitable for shopping malls, hotels, office buildings, schools, warehouses, factories, workshops, residential buildings, laboratories, cinemas and other commercial or indus

OEM & Custom Manufacturing-Custom dimensions, actuator configurations, materials and packaging can be provided according to project or distributor requirements.

Product Q&A

Q:What is a fire damper?

A fire damper is a safety device installed in HVAC and ventilation air duct systems. It is designed to automatically close when the temperature reaches the rated activation temperature, helping prevent the spread of fire through the duct system.

Q:What material is the fire damper made of?

The standard material is galvanized steel sheet, which provides good corrosion resistance, durability and structural strength.

Q:Can the size be customized?

Yes. We can manufacture customized dimensions according to your air duct size, installation space or engineering drawings.

Q:Does the damper close automatically?

Yes. The damper is equipped with a thermal actuator/fusible device. When the temperature reaches the specified activation temperature, the damper automatically closes.

Q:Is the fire damper airtight?

The product is subjected to airtightness testing, and the blades are designed to provide good sealing performance when the damper is closed.
