The world's first high-tech compact fan with patented bionic Bionic rotor loop is from Germany. Developed with the support of the Federal Economics Ministry and the bionic Dr. Rudolf Bannasch we make with the NB-ELOOP series against the currently most advanced fan in the world. The NB-ELOOP series sets new records in almost every category and convinced by our quality product. Newly developed storage and drive as well as the tried-NB cable management and a 12-piece mounting for vibration-free mounting complement the overall unique setup.

The new design eliminates the edge of the vertebrae are formed between the suction and pressure side of the wing tips. The tip vortices are here broken down into smaller vortex edge and spread evenly. The resulting at the blade trailing edge tip vortex can be reduced by vorticity guides to a minimum. The result is a significant improvement in glide ratio which leads to a reduction of the aerodynamic flow induced noise and improves energy efficiency.
