The Levitronix® Bearingless Fan System BFS is designed for demanding applications in microelectronics manufacturing. Based on active magnetic levitation, the fan impeller is suspended and driven by the magnetic field of the motor. The wide gap between impeller and stator ensures that there is no wear and therefore virtually no particle generation, making it the purest fan. As the impeller and stator are completely encapsulated, the fan is extremely resistant against aggressive media and is rated for use in explosive atmospheres.
