Latest generation of free-running centrifugal impeller. The impeller is designed as a centrifugal fan in steel or in ZAmid® technology with 5 backward curved blades and is available in variable motor technologies. Special features include bionic 3D-profile, with innovative design in the form of a specially warped blade geometry, as well as the blade leading edge developed according to the bionic principle and the V-shaped serrated trailing edge, which allows a wide range of performance. 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
