Product feature

  • Excellent aerodynamic characteristics and sound characteristic
    • Compared with 4rd generation Wind-surfer wheel: Performance increased by 5-10% and noise reduced 2-3dB(A) in the same condition.
    • Compared with axial/mixed flow fans, sound reduced by 10~15dB(A).
    • Fan internal with well organized airflow and the pressure loss is small.
    • Wide performance range of high efficiency.
  • Reliability design: safe and long life
    • FEA aided design, distributed evenly of stress for making operation reliable.
    • Performance loss caused by working point change.
    • High static pressure:Low RPM in same pressure.
    • Blade falling resistant: Safe.
    • Non-overloading .
  • Appearance design:Strong wind resistance, Novel and practical
    • Low streamline wind band: reduces wind load.
