Gearless direct drive hvls ceiling fan specially dedicated for large scale space. The streamlined fan blade adopts aerodynamics principles and advanced process , the diameter is from 2.4-7.2 meters, with coverage 14860m3/min. Only using the efficient direct drive motor, it can creat plenty of comfortable natural wind.
Motor will be inspected when producing ,and after gearless servo direct fan finished, we will inspect the motor with fan blades, in order to make sure the qualified fans to our clients. Quality is our culture.
