The latest generation of free running impeller in steel or ZAmid® technology with five backward curved blades. Blades designed with bionic 3D fluting in a unique twisted blade geometry. The tubercle on the blade leading edge, which is inspired by the humpback whale, and the V-shaped serrated rear edge allow for a wide range of high efficiency. Highest impeller and system efficiencies are achieved with the opening rotating diffusor.
The innovative corrugated blade surface diffuses the sound, ensuring the lowest possible sound level.
