Product Description

Introduction of product advantages: 
Our DC fan compares with the traditional AC fan: 

High efficiency and low energy consumption: DC fans usually use permanent magnet brushless motor, which eliminates the excitation current of induction motor and the frequency conversion loss of rotor core, so it has higher efficiency and lower energy consumption.

Low noise: Due to the optimization of the design of DC fans, they usually produce less noise than AC fans.

Long life: Using high-quality materials and bearings, DC fans can have a longer service life. 

Low electromagnetic interference(EMI): The electromagnetic interference of DC fans is small, which is especially important for electronic equipment requiring low interference environment.

Good speed regulation performance: the speed regulation of DC fan is simple and effective, and the wind speed can be adjusted as needed.

Environmental adaptability: DC fans can provide stable performance under various environmental conditions.

Energy-saving and environmental protection: DC fans are usually more energy-saving than AC fans when providing the same air volume.

Our faxial fans have the top-class quality and verious models, which can satisfy your needs. They produced by high quality plastics and aluminum materials.
