Applications
PP melt blown filter cartridge is a depth filter made from 100% virgin polypropylene microfibers with gradient density structure. The outer layer captures larger particles while inner layers trap finer contaminants, providing high dirt holding capacity and long service life. Widely used for RO pre-filtration, drinking water systems, chemical filtration, and industrial process water treatment. Available in micron ratings from 1 to 100 microns.
