The NB-eLoop fan features an innovative bionic loop design and outperforms conventional axial fans in nearly every aspect. For the first time, it has become possible to significantly reduce the noise generated in the airflow of the fan. At the same time, the usable performance has been increased while energy consumption has been reduced. The newly developed high-tech bearing and motor technology, along with numerous features and advancements such as a dust-protected motor and bearings, an anti-dust Makrolon rotor, and position-invariant magnetic levitation bearings, result in what is arguably the most advanced fan in the world. Advantage: extremely quiet operation, enhanced performance with reduced energy consumption. Developed in Germany with the support of the Federal Ministry of Economics.
