    The louvered ventilating fan is a widely used ventilating fan, which is mainly composed of auxiliary components such as motors, fan blades, wind frames, panels, shutters, and special pull-wire switches. Motors generally use single-phase capacitors to run asynchronous motors. Shaded pole motors are also used for ventilating fans below 150mm. The fan blades are generally injection molded with ABS and AS plastics, which are light in weight and high in strength. The wind frame is usually made of sheet steel stamping and spot welding, or plastic injection molding. The panel is made of plastic injection molding. Shutters are usually stamped and formed from sheet steel or tinplate.
