A primary efficiency filter is suitable for the initial filtration in air conditioning systems, primarily designed to filter dust particles larger than 5μm. There are three main styles of primary efficiency filters: panel, pleated, and bag types. The frame materials include paper, aluminum, and galvanized iron, while the filtering materials range from nonwoven fabric, nylon mesh, activated carbon, to metal mesh. Protective nets may consist of double-sided plastic-coated wire mesh and double-sided galvanized wire mesh.
Medium efficiency filters are widely used in the intermediate filtration of air conditioning systems, especially in environments with high dust concentrations. They utilize highquality synthetic non-woven filter materials, offering a large dust holding capacity. These filters are mainly designed to filter particles in the range of 1-5μm. Medium efficiency filters are available in bag, frame, and combination styles, providing advantages such as low resistance and high airflow.
High-efficiency filters are widely used in cleanroom systems for advanced filtration, primarily designed to filter dust particles larger than 0.3μm. Customization services are available based on customer requirements.
