　　The K series local fan is mainly composed of four parts: impeller, duct, collector, and stationary blade.

　　Impeller section: composed of blades and hub, the blades are made of thin steel plates and welded to the hub at the selected installation angle.

　　Shell section: composed of air ducts and brackets, all made of thin steel plates and profiles. The air duct is cylindrical with a certain gap between it and the impeller.

　　Collector section: composed of a collector ring, flange, collector cover, protective net, etc. The wind collecting ring is a circular arc streamlined shape, which can reduce the loss of airflow inlet and is made of thin steel plate.

　　Static blade cascade: composed of cylinders, flanges, stationary blades, etc. The two ends of the blade are welded to the guide vane on the cylinder according to the selected installation angle, and the pressure of the fan is increased.
