Centrifugal fan with backward inclined straight blades
Févi international
OF SLIGHTLY CLOGGING DUST
The flat shape of the blades facilitates cleaning of the impeller and also its protection by wear plates.
The wear takes place in a well-defined zone (blade trailing edge against the back disc) which provides the means for effective protection of the impeller by wear plates and/or hard metal coating.
The blade's incline to the rear provides for good efficiency and low noise levels
to be obtained.
