Dust-Resistant (DR) MagLev Motor Fans Sunon Dust-Resistant (DR) MagLev Motor Fans are based on magnetic principles/forces that propel the fan and ensure stable rotation over its entire 360° of movement. The design utilizes the attraction of magnetic levitation force and eliminates the wobbling/shaking problems of traditional motor fans. The blades are suspended in the air during rotation so that the shaft and bearing do not come into direct contact with each other, causing friction. These features result in a fan with a low acoustic noise level, high-temperature endurance, and a longer lifespan. Sunon DR MagLev Motor Fans are also RoHS compliant.
