The NB-eLoop fans feature a new bionic loop design and surpass traditional axial fans in almost every respect. The noise generated in the airflow of the fan has been significantly reduced. At the same time, the efficiently usable power has been increased and energy consumption 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. Advantages include extremely quiet operating noise and increased performance with reduced energy consumption. Developed in Germany with the support of the Federal Ministry for Economic Affairs and Energy.
