Centrifugal Fan

The forward-curved impeller is manufactured with integrated blades, which give the fan high rigidity and high performance. The bearings are rigid, self-aligning ball bearings that are sealed and lubricated for the entire service life.

The small-series design consists of side frames and a support crossbar, while the large-series design includes a triangular frame and bearing supports.
