The NB-eLoop fan features a new bionic loop design and outperforms conventional axial fans in almost every respect. Noise generation in the airflow of the fan has been significantly reduced. At the same time, the efficiently usable power has been increased, and energy consumption has been lowered. The new high-tech motor and bearing technology, along with numerous features and developments such as dust-protected motors and bearings, a Makrolon dust rotor, and magnetic bearings, make this fan the most advanced in the world. Benefits include extremely quiet operating noise, increased performance with reduced energy consumption. Developed in Germany with support from the Federal Ministry of Economics and Technology.
