The initial efficiency filter cotton of magnetic levitation fan has the characteristics of high dust holding capacity and low resistance, and strong flame retardancy; Long service life, can be used multiple times after cleaning, economical and practical. It can replace fiberglass filters and can also be processed into frame, paper frame, and aluminum frame designs. The primary filter cotton of the magnetic levitation fan mainly filters dust particles larger than 5 μ m; Made by processing high-performance and high-strength synthetic fibers in an incremental structure.

1. The initial effect filter cotton of magnetic levitation fans is generally used at the suction inlet of ventilation equipment and air control systems as a pre filter or coarse filter directly in contact with outdoor air;
