The DKT type external rotor centrifugal air conditioning fan is a multi wing centrifugal fan with high air volume, low noise, compact structure, sturdy and durable, beautiful appearance, and easy installation and use. This fan is widely used in various air conditioning units, air curtains, cooling and heating fans, etc. It can also be used for indoor ventilation and air exchange in industrial and mining enterprises and public places. The medium it transports is air and other unnatural gases that are harmless to the human body. The gas is not allowed to contain particulate matter and has a dust content of no more than 150mg/m3.
The DKT external‐rotor centrifugal air‐conditioning fan is built around three principal components: the impeller, the housing, and the external-rotor motor. The impeller is riveted by dozens of forward-curved blades, a wheel cover, and a middle disc. All components are manufactured using stamping dies. The fan demonstrates excellent air performance, having undergone static and dynamic balance correction for smooth operation. The casing is formed by lockseaming and hemming with specialized equipment, featuring sturdiness and durability as well as a beautiful and elegant appearance. The motor adopts an outer rotor type, built into the casing and directly connected to the impeller, ensuring a compact structure.
