High Efficiency External Rotor Duct Axial Fan for Quiet Airflow Solutions

Our External Rotor Duct Axial Flow Fan series delivers superior ventilation performance with minimal noise output, making it ideal for commercial and industrial applications where low noise duct fans are essential.

The external rotor axial fan features an innovative motor design where the rotor rotates outside the stator, providing compact dimensions and excellent airflow efficiency. These duct mounted axial fans are engineered for optimal performance in HVAC systems, ventilation ducts, and air handling units.

  • Ultra-quiet operation with noise levels as low as 45 dB(A)
  • Energy efficient design reduces power consumption by up to 30%
  • Compact construction saves valuable installation space
  • Robust external rotor motor ensures long service life
  • Easy maintenance with accessible components
  • Multiple size options for different duct configurations
