Products Description
String wound cartridge filters offer reliable, cost-effective depth filtration by trapping particles throughout a graded, multi-layer winding of yarn. Available in polypropylene, nylon, polyester, and blended fibers, these cartridges provide customizable micron ratings, robust chemical resistance, and stable flow performance across a wide range of industrial, commercial, and residential applications.

Selection guide
FAQ
Q: How do string wound cartridge filters outperform pleated cartridges?
A: 3-5× higher dirt holding capacity and superior depth loading for high-sediment applications, though with slightly higher initial ΔP.
Q: Do you offer non-standard lengths or end caps?
A: Yes – Custom lengths (5"–60") and any end cap configuration (double open, threaded, grooved) in 48hrs.
Q: How to optimize cartridge life in high-sediment systems?
A: Use progressive density winding (available on request) – captures large particles first to prevent surface blinding.
