Solution to prevent the return of the centrifugal fan

Centrifugal fan has been widely used in life and work with many advantages. Usually, when designing the centrifugal fan, it will pay more attention to the noise and air volume, but it may be the backflow problem to be ignored. If you ignore this problem, then in the later use, it will be found that there are many problems and trouble. Generally speaking, the centrifugal fan equipment will appear to return the problem, the main reason is that the design is unreasonable. Because most of the time in the design process, only consider the air volume or noise requirements, so in the actual use, its exit will appear reflux phenomenon.
