CF-11 Low-noise Multi-wing Centrifugal Fan is designed and manufactured by our company to meet the needs of the growing purification industry and environmental protection and noise reduction. During the design of the fan, the multi-objective optimization design method for various aerodynamic parameters such as noise and efficiency is adopted to achieve the optimal performance matching of the whole machine. With good aerodynamic performance, the impeller has a good dynamic balance, so it is stable in operation, low in noise, large in flow, small in vibration and long in service life. It is widely applicable to the kitchen exhaust, smoke extraction or ventilation in public places such as unit canteen, hotel restaurant and catering shop, and suitable for the use of food machinery, chemical machinery, plastic machinery and other production equipment. Wide application and strong adaptability.
