Fire Damper

• Fire Damper (Air Volume Control Damper)

   

  The fire damper, also known as an air volume control damper, is an essential component at the end of central air conditioning systems in industrial plants and civil buildings. It is typically installed in ductwork to regulate airflow in branch pipes and control the mixing of fresh and return air. This product plays a key role in ventilation, air conditioning, and air purification systems.

Excellent Sealing Performance: Leakage rate ≤0.5% under 1000Pa pressure and 10m/s air velocity.

Precise Flow Regulation: Offers equal percentage flow characteristics for accurate air volume control.

Custom Sizes Supported: Non-standard dimensions can be customized upon request.

Low Noise Operation: Operating noise ≤45 dB(A), ensuring quiet performance.

Corrosion Resistance: Made from carbon steel, galvanized steel, aluminum alloy, or stainless steel to suit various applications.

Easy Manual Adjustment: Simple to operate in systems that do not require automation.

Smart Electric Actuator (Optional): Supports 4–20mA input for remote and automatic control.

The valve body is constructed from 2mm galvanized steel plates using cold rolling technology, then assembled with CO₂ gas shielded welding or spot welding for galvanized sheets. The blades are made of 1mm corrugated galvanized steel or 2mm G235 steel and are securely spot-welded to square or round shafts to ensure strength and durability.

This product is widely used in industrial and commercial HVAC systems, particularly in areas that require accurate airflow regulation. It is ideal for fresh air intake, return air regulation, and air mixing in various ventilation modes.
