· Performance Overview CF-11 multi-wing low noise centrifugal fan is to meet the purification of industrial and environmental noise of the growing needs and designed and manufactured. Fan with noise, aerodynamic efficiency and other parameters in the design of multi-objective optimization design method to achieve the best performance of the machine match. It has a good aerodynamic performance. Impeller and pulley are strictly balancing more positive, so the smooth operation, low noise, traffic, vibration, long service life. Widely used in kitchen exhaust unit canteens, hotels, restaurants, eateries and other public places, fume extraction or ventilation purposes, and suitable for use in the food processing machinery, chemical machinery, plastics machinery and other production equipment. Versatile and adaptable.
