Industrial Large Ceiling Fan for Transportation and Logistic Usage of permanent magnet synchronous motor, makes the motor and wheel shaft as a whole, because the motor can be installed on the wheel shaft directly. Share Inquire Now Next Product Usage of permanent magnet synchronous motor, makes the motor and wheel shaft as a whole, because the motor can be installed on the wheel shaft directly. It eliminates a gearbox, completely sealed, truly maintenance-free.      The use of aerodynamic principles and advanced technology streamlined ultra-long fan blade brings large air volume coverage range. It transports a large amount of air to form a 0.5-3m air layer on the ground, brings a large air volume coverage.      The HVLS fan has an efficiency of 85% within the speed range, especially under 70% of the highest speed load, the motor efficiency can reach 90%.   The use of fans together with air conditioners can save electricity by more than 32%. For indoor environment with air conditioners, the industrial fans can accelerate the flow of cool air to get a great electrical energy saving.   High-performance controller with frequency control system, is easy to operate. Just need to rotate the speed control button, can meet the requirements of different wind speeds.
