The first high-tech compact fan worldwide with a bionic loop rotor is now available with a subtle black for extensive design possibilities. NB-eLoop fans stand out due to the new bionic loop form and are superior to common axial fans in almost all respects. It reduces the noises caused by the air stream in the fan dramatically. At the same time, the effectively usable performance increase with reduced energy use. With newly developed high-tech bearing and engine technology, eLoop series features dust protected engine and bearing, anti-dust-Macrolon rotor, position invariant magnetic bearing making this the most advanced fan in the world.
