PP Core Filter Cage for String Wound Filter Cartridge | 10-70 Inch Standard & Custom Length Supply

AALFilter PP Core Filter Cage is a high-quality polypropylene support core designed for string wound filter cartridge manufacturing. It provides the internal structural support required during the winding process, helping maintain cartridge strength, dimensional stability, and filtration performance.

AALFilter supplies a complete range of PP core cages from standard lengths including 10 inch, 20 inch, 30 inch, and 40 inch, as well as special long-length options such as 50 inch and 70 inch PP core filter cages.

Compared with conventional filter cartridge sizes, 50-inch and 70-inch string wound filter cartridges are less frequently required in the market, making it challenging for many filter manufacturers to maintain dedicated production equipment and inventory for these special lengths.

By sourcing 50 inch and 70 inch PP core cages from AALFilter, string wound filter cartridge manufacturers can easily expand their product range, reduce manufacturing complexity, and avoid additional investment in special tooling or extrusion production.

Made from high-quality polypropylene material, AALFilter PP Core Filter Cages offer excellent chemical resistance, stable dimensions, and reliable mechanical support, making them suitable for industrial filtration applications including water treatment, chemical processing, electroplating, and process liquid filtration.
