Impellers
The impellers of the centrifugal blowers from FIMA are covered or semi-open design with blade which are curved backwards or ending radially. The selection of a suitable geometrical arrangement for the impeller and the matching casings is the pre-requisite for high efficiency, low noise and long service life.
Welded blade joints extending on both sides prevent crevice corrosion and improve the strenght of the impeller. Dynamic balancing ensures smooth running of the blowers.

In most applications covered impellers with blades which are curved backwars are used. Semi-open impellers with radially ending blades are used to convey gases with a high particle content. This substantially avoids any imbalances due to incrustations.
