cross flow blower are also known as local fans. It is a kind of fan commonly used by industrial and mining enterprises. It is different from ordinary fans. Its motor and blades are all in a cylinder and the shape is a cylinder. For local ventilation, easy installation and ventilation. The ventilation effect is obvious and safe, and the wind can be used to supply air to the designated area.

　　The characteristic of the cross flow blower is that the fluid flows through the fan impeller twice, the fluid flows in radially first and then flows out radially, the intake and exhaust directions are on the same plane, and the exhaust body is evenly distributed along the impeller.

　　cross flow blower are also known as cross flow blower in the market. cross flow blower are generally understood from the following points.

　　1. cross flow blower impeller: The impeller of the cross flow blower is a relatively long barrel-shaped fan blade. In this way, the design of the large air inlet and the large air outlet greatly reduces the noise under the same air volume.

　　2. Do double-sided dynamic balance: The impeller mentioned above is a long cylinder, which is processed by hardware. Inevitably, the balance can be fairly standard.

　　3. The impeller of the cross flow blower has been tested by engineers to simulate air volume, air pressure, noise and other software tests for many times. It's more than simple design, drawing and shaping. They are all cleverly designed to avoid "unequal distances, unequal angles, and different centers".
