The 4-72 Model Centrifugal Fan conveys air and other non-flammable, non-toxic gases that do not corrode steel. No viscous substances are permitted within the system. The dust and hard particulate content must not exceed 150 mg/m³, and the gas temperature must not exceed 80°C. This fan employs backward-curved blades with superior aerodynamic properties, delivering smooth operation, high airflow, minimal vibration, high efficiency, and extended service life. It is widely used for ventilation in industrial and mining enterprises, large-scale buildings, hotels, and restaurants.

Type A: Direct drive with the motor, where the fan impeller and casing are directly fixed on the motor shaft and flange plate.
Type C: Equipped with a cantilever support device, driven by a belt.
Type D: Equipped with a cantilever support device, driven by a coupling.
