centrifugal fanIt belongs to a kind of fan, but does not belong to the Roots fan, centrifugal fan structure is relatively simple, generally only the casing, impeller, bearing housing, bearings, and other simple accessories composition. Centrifugal fan and Roots fan a big difference is that the Roots fan is low-pressure inlet and high-pressure outlet, while the centrifugal fan is just the opposite, is high-pressure inlet and low-pressure outlet. But centrifugal fans in real life is very wide range of applications, small to the kitchen hood, large to the building exhaust fan are all belong to the centrifugal fan in a kind of.

Centrifugal fans are surprisingly widespread, so how do we choose?

First of all, we have to first recognize the definition of centrifugal fan, centrifugal fan and axial fan structure is very close, axial fan structure is more simple, in daily life and please use more in industry, for example, the electric fan is the axial way of operation, but no matter what, usually centrifugal fans and axial fans are classified into one category.

Centrifugal fan selection in the parameter selection and Roots fan close to the first to know the fan pressure, power, flow, centrifugal fan in the flow is called air volume. Axial fan selection is a little different, axial fan is divided into more types to be classified according to the material, according to the use of classification, according to the use of classification requirements for selection. Selected according to the parameters of the corresponding model, the same can be based on the principle of selection of Roots fan to finalize the type of centrifugal fan.
