Floor-standing fan CF-11 series

low-noiseIP54centrifugal

SERIES LOW-NOISE MULTI-WINGS CENTRIFUGAL FAN CF-11 series multi-vane low noise centrifugal fan is designed for the company which is suitable the evolving trend of requirements, what is purification of industrial, environmental protection and noise reduction. According the fan noise, efficiency and other aerodynamic parameters of multi-objective optimization design methods, the centrifugal fan match other machines can achieves the best performance. The impeller and the belt pulley are inspected by strict dynamic balance emendation, so the fan has the characteristic of smooth operation, low noise, small vibration, long use time and so on. It can be widely used in the dining room, guesthouse,restaurant, eating house for kitchen ventilation，exhaust. And the centrifugal fan is suitable for cereal processing machinery, chemical engineering machinery, plastics machinery of the manufacturing equipment. APPLIED CONDITIONS Max.
