NB-eLoop® series NB-eLoop fans stand out due to the new bionic loop form and are superior to common axial fans in almost all respects. For the first time it was possible to reduce the noises caused by the air stream in the fan dramatically. At the same time, the effectively usable performance was increased and the energy use was reduced. The newly developed high-tech bearing and engine technology as well as the many features and further developments like dust protected engine and bearing, anti-dust-Macrolon rotor, position invariant magnetic bearing make this the probably most advanced fan in the world.
