High-quality Cross flow blowers are mainly composed of impeller, air duct and motor. The impeller material is generally aluminum alloy or engineering plastic. High-quality Cross flow blower aluminum alloy impeller has high strength, light weight, high temperature resistance, and can maintain stable operation without deformation; plastic impeller is injection molded by mold and then ultrasonically welded.

　　High-quality Cross flow blower air ducts are generally stamped and formed from metal sheets, and can also be cast from plastic or aluminum alloys. The casing adopts a streamlined design, which can effectively reduce the loss of airflow and greatly improve the working efficiency of the fan.

　　The motor is the power part of the high-quality Cross flow blower, which can be powered by AC or DC. The AC power supply mainly includes a shaded pole motor and a capacitor starter motor, and the DC power supply is a DC brushless motor. The drive motor is generally installed flexibly with the impeller and fixed on the air duct.

　　Advantages and disadvantages of high-quality Cross flow blowers

　　(1) The axial length of the high-quality Cross flow blower is not limited, and the length of the impeller can be arbitrarily selected according to different needs; (2) The airflow flows through the impeller and is affected by the two forces of the blades, so the airflow can reach a long distance; (3) The high-quality Cross flow blower has no turbulence, and the air outlet is uniform; (4) Because the airflow is forced to turn in the impeller, the head loss is large and the efficiency is low.
