The centrifugal fan is a marvel of engineering, meticulously crafted from a robust fan unit, essential auxiliaries, and a sophisticated control and monitoring system. The fan unit itself is a harmonious assembly featuring a rotor part, including the dynamic impeller and the main shaft, and a static part composed of a durable housing, an inlet box, and an air inlet. Further enhancing its precision and performance, it includes a damper among other components. The auxiliaries, indispensable to its operations, encompass a powerful motor, a hydraulic coupling, an actuator, and more, ensuring seamless functionality and superior reliability.
Our centrifugal fans boast a versatile range of transmission methods, tailored to meet diverse operational needs. These include the motor direct connection (A type), the belt transmission (B, C, E type), the coupling transmission (D type), and the innovative coupling transmission with an inlet box (F type). Notably, the E type and F type are engineered to be designed as double suction fan types, offering enhanced efficiency and flexibility for demanding applications.
