String Wound

Description

PP String Wound series filter cartridges deliver a high reliable and consistent filtration of fluids in a wide range of application. The continuously graded pore structure of the filter creates a network of tapered passages that capture contaminants throughout the media. The true depth filtration prevents the cartridge from blinding off when filtering fluids containing deformable particles of gels.

This cartridge is constructed in various materials which offering an excellent chemical compatibility with variety of fluids and temperature range. The extended core option eliminates the need for expensive housing hardware and allows for quick and easy cartridge change-out.

Benefits

  • Different of media and center core options allows an excellent compatibility for different kinds of fluids.
  • True depth filtration enabled high dirt holding capacity and is ideal for removing deformable particles of gels from process fluids.
  • Polypropylene or Cotton with FDA CFR Title 21 listed components are suitable for food and beverage applications.
  • Available in removal ratings from 0.5 to 150µm.
  • Large (4”) diameter with 10” and 20” length cartridges are available for use in Plymouth Big Blue filter housing.
  • Extended core option eliminates the need for expensive housing center posts.
