String-Wound Depth Filter – Polypropylene Cartridge

Our string-wound depth filters are precisely engineered to deliver effective sediment removal through a deep pore structure and enhanced surface area—ideal for pre-filtration in purified water systems and other critical-use applications.

Key Features

  • String-Wound Polypropylene Media – Durable polypropylene fiber tightly wound around a rigid polypropylene core in a precise pattern to maximize surface area and dirt-holding efficiency.

  • Depth Filtration Design – Multi-layer winding traps particles progressively, from large to fine, preventing surface blinding and extending service life.

  • Multiple Diameter Options – Available in Slim Line (2.5″ OD), Regular (2.75″ OD), and Big Blue (4.5″ OD) formats to fit a wide range of standard filter housings.

  • Wide Micron Ratings – Offered in nominal ratings from 0.5 to 100 μm to meet varied sediment removal needs.

  • Robust Construction – Withstands operating temperatures from 40°F to 165°F (4°C to 73.9°C) while maintaining high flow rates and minimal pressure drop.

  • Economical & High-Capacity – Lower maintenance and longer life compared to many surface filters.

  • Safe & Versatile – 100% polypropylene construction is resistant to bacteria growth and chemical attack.

Applications

  • RO Pretreatment & High-Purity Water Systems – Protects reverse osmosis membranes and downstream purification stages.

  • Whole-House & Point-of-Entry Filtration – Suitable for residential, commercial, and light industrial sediment reduction.

  • Medical, Laboratory & Pharmaceutical – Provides clean feed water for critical processes.

  • Industrial Pre-Filtration – Ideal for removing suspended solids from process water in food, beverage, and manufacturing facilities.
