Huada HDB series permanent magnet variable frequency wall fan is a new type of industrial fan specially designed for factories and workshops with limited ventilation space. Adopt self-designed frequency conversion speed regulation, high efficiency and energy saving permanent magnet synchronous motor. It has the advantages of low noise, small volume, light weight and beautiful appearance.

Fans adopt a unique airfoil blade design with a diameter of 0.9-2m. It adopts the principle of aerodynamics and advanced technology to produce a natural breeze system through the circulating airflow field formed by the powerful air stirring force. The human body will feel the three dimensional wind from all directions,increase the evaporation area of sweat and improve the comfort. At the same time, avoid using the traditional high speed fan to cause various health problems of human body under directional wind all the year round, and greatly improve the environmental comfort. HDB series wall fan can be adjusted according to the actual demand of different occasions, the wind speed is 1m-6m.Adjustable within 7m/s. In the open space, the maximum air supply distance of an energy-saving fan is up to 24m.
