Filter Media Options
Start with the yarn, then select the support core, filtration grade and cartridge dimensions around your process.
PP String-Wound Filter Cartridges
Polypropylene yarn wound around a support core for particulate filtration of water and compatible process liquids. Match the grade, core and dimensions to your installation.
Cotton String-Wound Filter Cartridges
Cotton yarn with a selected support core for compatible oils and process liquids. Consider fluid chemistry, temperature and the full cartridge construction together.
Glass Fiber String-Wound Filter Cartridges
Glass fiber yarn and core combinations for applications where temperature and process compatibility shape the material choice. Review the exact grade and support arrangement.
String-Wound Filtration Principle
Explore the wound yarn structure, follow liquid through the filter wall and into the support core.
Crossing yarn courses build the filtration structure.
Yarn is wound in crossing courses around a perforated core. The winding pattern forms the depth of the filter wall.
Liquid travels from the outside through the yarn pack. Particles are retained within its fibrous structure according to the selected grade.
Filtered liquid passes through the support tube openings, collects in the center bore and continues toward the housing outlet.
Yarn & Core Options
The filter yarn and support core have different roles. Select them together with the liquid, working conditions and housing.
- Filter yarn
- Crossing yarn courses create the fibrous filter wall. Material and winding construction contribute to the selected filtration grade.
- Support core
- A perforated polypropylene or metal tube supports the wound pack and provides a path into the central collection channel.
- Cartridge dimensions
- Nominal length, outside diameter and bore diameter determine the installation envelope. Compare actual dimensions when replacing an existing element.
- End arrangement
- Plain double-open ends and application-specific end fittings need the correct housing seating and sealing arrangement.
