The latest generation of free running wheel in steel or ZAmid® technology with 5 backward curved blades. Impeller with bionic 3D fluting thanks to innovative design in the form of a specially wound blade geometry. The tubercle on the blade leading edge, which is modelled on a humpback whale, and the V-shaped serrated rear edge allow a wide characteristic map range.

The highest impeller and system efficiencies are achieved in conjunction with an opening rotating diffusor. In combination with the innovatively rippled blade surface, diffuse sound radiation takes place, ensuring the lowest possible sound level.
