The SDF series of fans are divided into four models: 2.5A, 3.5A, 4A, and 5A.

The fan introduces a segmented arc wind tube with guide vanes to improve the air intake and outlet efficiency, while improving the rotating airflow that diffuses to the outer circle after the fan exhausts the air, making the airflow less likely to scatter, and the efficiency is improved significantly. The air volume is concentrated and the scattering is small. Compared with traditional axial flow fans, the range of high-speed airflow is increased. When the distance from the air outlet is more than 1.5m, the central wind speed can be increased by more than 3 times.

The SDF series axial flow fan is suitable for various applications that require high wind speed cooling.

Product Parameter

Product Performance

This series of fans have concentrated air volume, high wind speed and long range, it’s suitable for occasions that require long-distance/short-distance, short-time rapid cooling (ventilation). At the same time, due to the special structure, its performance is little affected in narrow locations with limited air inlet, but it can also play its full functions.
