Wheel feature

  • Air performance design
    • Optimized design of CFD flow field simulation, repeatedly validated.
    • Impeller cutting the air flow asymptotically, air flow direction is stable and high in consistence.
    • 3D curved blade design: Guide air to flow smoothly and reduce turbulent current.
  • Structure performance design
    • Computer aided design of CAE for optimizing structure performance.
    • The connection technology of hub and blade is highly reliable.
    • Blade end vibration effectively reduced by aided design, prevent blade distortion or breaking after long time running.
  • Advanced process
    • The 3D curved blades are formed by mould pressing to ensure precision.
    • Special tooling is adopted for hub to ensure precision.
    • Special tooling is adopted for the installation of blade to ensure performance.
  • High balancing level
    • Balance quality grade up to G2.5 (Typical products are balanced to G6.3 only).
    • Keep running safely and steadily for a long time.
    • Extend service life of the fan.
  • Diverse selection
    • 16 kinds of specifications, the maximum impeller diameter is 1800mm.
    • Impeller material: carbon steel, stainless steel, alloy aluminum, FRP coated.

Product feature

  • Performance characteristics: Smooth airflow and saving energy
    • Patented propeller-type axial wheel: Excellent aerodynamic characteristics and sound characteristic.
    • Fan internal with well organized airflow and the pressure loss is small.
    • The clearance between the impeller and tube wall is limited. To be reduced the energy loss caused by the secondary flow and more efficiency.
    • High efficient area width without overloading.
  • Appearance design:Strong wind resistance, Novel and practical
    • Low streamline wind band: reduces wind load.
    • Pitched wind band baffle: drains snow rapidly by gravity.
    • Suitable for strong winds.
    • Modernize buildings with enhanced taste.
  • High reliable design: safe and long life
    • FEA aided design, distributed evenly of stress for making operation reliable.
    • Performance loss caused by working point change.
    • Multi-reinforced ribs: greatly increase rigidity and reduce weight.
