HFBD series is an innovative permanent magnet frequency conversion large ceiling fan designed for high space environment, through the bionic natural wind technology, combined with high efficiency energy saving and intelligent control, to provide a full range of three-dimensional ventilation and cooling solutions for industrial, commercial and public space, taking into account human comfort and energy efficiency.                                                                                        

Core technology advantages   

1. Permanent magnet frequency conversion drive system  

     Equipped with self-developed permanent magnet external rotor motor, the energy efficiency conversion rate is increased by more than 30%, supporting 1-5m/s stepless speed regulation, accurately matching the needs of different scenarios.  

     Inverter technology realizes soft start and low load operation, reducing energy consumption by 40-60% compared with traditional fans.

2. Bionic natural wind system   

     Adopting aerodynamic wing-type blades (2-7.3m in diameter), it promotes the airflow to sink vertically and spread horizontally, forming a three-dimensional circulating wind field at a height of 3-5 meters.  

      Simulate the natural breeze body feeling, wind speed fluctuation is soft, to avoid the traditional high-speed fan directional strong wind caused by health hazards.

3. Ultra-quiet structure design  

      Lightweight and compact structure of the whole body, operating noise ≤ 45dB (A), suitable for places with strict requirements for silence.
