The DC blower uses direct current to convert it into mechanical energy to drive the wind wheel to rotate. The air inlet and outlet are in a vertical wind direction, and the air is continuously compressed to generate a large amount of air for blowing.

Frameless DC fan is the fluid that frameless DC fan through the fan impeller twice, the fluid flows in the radial direction and then frameless DC fan out in the radial direction.

A cross-flow fan is a fluid that cross-flow fan through the fan impeller twice, the fluid flows in the radial direction and then flows out in the radial direction. The intake and exhaust directions are in the same plane

DC axial fans are very versatile, that is, the airflow in the same direction as the axis of the blades, such as electric fans, air conditioners, and external fans are fans that operate in axial flow.
