Cross Flow Fan Introduction
The cross flow fan, also known as a tangential fan or transverse flow fan, primarily consists of three parts: the impeller, air duct, and motor. The impeller is cylindrical with multiple blades and has a forward-facing multi-wing shape. As the impeller rotates, airflow enters through the open section of the impeller into the blade grid, passes through the interior of the impeller, and is discharged from the opposite side of the blade grid into the volute, thus forming the working airflow.
