Axial-flow fan, which is characterized in principle, is that the fluid flows along the axial direction of the fan blade. Therefore, from this point of view, the fan and the exhaust fan used in the home, is similar to the axial-flow fan principle. The centrifugal fan uses centrifugal force to throw the fluid out of the circumference after the fluid is inhaled from the axial direction of the fan, so the blower and the range hood are similar to the centrifugal fan in principle.
Axial flow fan, centrifugal fan and blower fan, they are all belong to this category, but technically it is not what the comparability between the three, because belong to different category. Moreover, from another angle, axial flow fan and centrifugal fan, the two can be used as a blower to use.http://www.jnblower.com/
