It's our pleasure to introduce the HVLS (High Volume- Low Speed) fan to you——EURUS Series super large energy-saving fan with a diameter up to 7.3M.
Kale Airfoil Blades, which are streamlined, are developed with the advanced technologies and the principle of aerodynamics. Just with a power of 1.5KW or less, the blades are able to drive a mass of air and then produce a large scale of natural wind, which leads to the double functions of ventilation and temperature cooling. Compared with the traditional HVAC conditioners and small high-speed air blower, the fan has superior advantages in application, and is the ideal solution to ventilate and cool the air in large area.

Main Components Tech

  • Motor system
  • Hub
  • Control system
  • Fan blade technology
  • Winglet
  • Compared with common geared motor

    Adopt imported Germany LENZE motor, and work with Germany company to develop geared motor for HVLS products.
    1. Use low backlash assembly process and gear grinding technique, lower noise
    2. Strength the bearing frame structure, increase oil seal and strength the motor structure with trapezoidal shaft structure, higher safety
    3. Adopt IE2 high efficient motor, save more 5-10% than IE1
    4. Passed CCC, CE, UL certificates

  • 1500T Hot forging & numerical control machining & CNC precise machining

    The hub made by 1500T Hot forging, numerical control machining and CNC precise machining. Forging is able to confirm the consistency of metal structure, which can keep the inside structure and the outside shape of forged pieces consistent. Complete streamline structure of the metal confirms the best mechanical property of the hub. By CNC machining, the precision tolerance has been controlled in 100um, which guarantees the precise dynamic balance of the hub.

  • Top level electrical configuration in HVLS industry

    Schneider brand electrical sets, with buildin safety protection module which will shut down the output automatically in case of some accidents.
    Germany brand control cabinet, passed EMC by SGS and CCC certificates, meanwhile, passed anti-creeping tests which shields electromagnetic interference effectively.
    Protection level is IP55, passing UL, EMC,LVD, ROHS certificates.

  • New Kale Airfoil Blades

    Adopt imported special high strength aircraft grade magnalium, PVFD processed in surface,and aerodynamics fan blade design. Kale new special patent—Kale Airfoil Blades,there is 3 sets strengthening support system inside,which increases the strength of fan blade and avoids the drop of fan blade tail and the loss and fatigue of fan blade to connecting pieces completely.

  • Aerodynamics Winglet

    The kind of empennage isalways seen among airplanes and motorcycle races, but it’s not designed for beauty. Eddies will be formed in the end of the streamlined fan blade while airflow is running. With winglet, this part of energy loss will be avoided,fan will run steadily, which will bring economic effect.
