The CF-11A low-noise multi-wing centrifugal fan is designed and manufactured by our company to meet the growing needs of the purification industry and environmental noise reduction. The fan adopts a multi-objective optimization design method for aerodynamic parameters such as noise and efficiency during the design process, achieving optimal performance matching for the entire machine. It has good aerodynamic performance, and both the impeller and pulley have undergone strict dynamic balancing, resulting in stable operation, low noise, large flow, small vibration, and long service life. It is widely used for kitchen exhaust, fume extraction, and ventilation in public places such as canteens, hotels, and restaurants, and is suitable for use in production equipment such as grain machinery, chemical machinery, and plastic machinery. It has a wide range of applications and strong adaptability.
