CF-11 Series Low-Noise Multi-Wing Centrifugal Fan with High-Efficiency Aerodynamic Design and Durable Construction

The CF-11 series is a professional low-noise multi-wing centrifugal fan specifically engineered for applications requiring quiet and efficient air movement. Its advanced multi-wing impeller design delivers exceptional aerodynamic performance while minimizing operational noise, making it the ideal choice for noise-sensitive environments in both industrial and commercial settings.

This fan series is suitable for conveying clean air and non-corrosive, non-flammable gases free of viscous substances. It features a compact structure, reliable operation, and a wide range of configuration options to meet diverse ventilation requirements. All models are available in dual voltage (380V/220V) for most sizes, ensuring compatibility with different power systems worldwide.

• Ultra-Low Noise Operation - Advanced multi-wing forward-curved impeller design significantly reduces aerodynamic noise. Noise levels as low as 67 dB(A) for low-speed models. Balanced rotating components eliminate mechanical vibration and noise. Perfect for environments where quiet operation is critical.
• High-Efficiency Aerodynamic Design - Optimized blade profile ensures maximum air delivery with minimal energy consumption. Flat performance curve provides stable operation across a wide flow range. Multiple speed options (2830 r/min, 1450 r/min, 960 r/min) for precise performance matching.
• Durable & Reliable Construction - Robust steel casing with high-quality paint finish for corrosion resistance. Precision-balanced impellers for smooth, vibration-free operation. High-quality motors with long service life and low maintenance requirements.
• Flexible Configuration Options - 9 standard models with power ratings from 0.25 kW to 5.5 kW. Dual voltage (380V/220V) available for most models. Multiple rotation speeds to suit different airflow and pressure needs. Special variants (marked with *) available for specific application requirements.

Note: Models marked with * are special variants with optimized performance for specific applications. All parameters are based on standard conditions (air temperature 20 °C, atmospheric pressure 101300 Pa, air density 1.2 kg/m³).
