Product Applications

The DKT external rotor fan is widely used in various air conditioning units, air curtains, and heating/cooling fans, and also plays a significant role in ventilation systems for industrial enterprises and residential buildings. The double-inlet centrifugal fan mainly consists of key components such as the impeller, volute, and motor.

The impeller features forward-curved blades and is constructed with a wheel cover and central plate, all riveted together. Each component is manufactured using stamping molds, ensuring precise dimensions, reliable profiles, and excellent aerodynamic performance. The impeller undergoes dynamic and static balancing corrections to ensure smooth operation and low noise.

The volute is coated using specialized equipment, making it both durable and aesthetically pleasing. The motor is of the external rotor type, housed within the volute and directly coupled with the impeller. This design is compact, providing smooth rotation and low noise.
