As mentioned on the previous page, the DR MagLev technology includes the S & C design. This innovative technology brings the fan components together in a way that provides the best resistance to dust invasion. As shown here, the previous MagLev model brought together the separate components of fixing ring, dust cap, and bearing. On the DR MagLev model with the S & C design, Sunon clipped together the stator, bobbin, plastic tube, and bearing to ensure the best dust resistance.
