Graded Density Illustrated

Spun Bonded Cartridge filters are manufactured through a process that thermally bonds pure Polypropylene microfibers with lower density at the outside surface and progressively higher density toward the center. This is Graded Density. This fully automated manufacturing process assures consistent quality, filter to filter, year in and year out.

Spun Bonded Cartridges can be used either as a pre-filter or final filter for industrial, chemical process, pharmaceutical, food/beverage, cosmetics, water and other applications.
