Porous Metal Filters offer a wide range of cleanable stainless steel filter cartridges, in many different markets and applications. Our cartridges fit in most commercial housings, or we can design and manufacture a cartridge to meet custom applications.

Media design:

316L Stainless Steel
  • Pleated.
  • SinterPore® sintered fiber/mesh laminate.
  • Multi layer sintered mesh and fiber metal felt pleated to increase filtration. The fiber metal felt offers depth filtration, while the mesh offers support and rigidity. Fiber/mesh promotes finer filtration, increased dirt holding, and improved permeability.
  • SinterPore® sintered mesh laminate.
  • Multi layer sintered mesh pleated to increase filter area and filtration life. These elements are easily cleaned and back flushable.
SinterPore® sintered laminate tube filter
  • Multi layer sintered mesh media that formed and welded into a cylinder. SinterPore® filter elements are back flushable, rigid, surface filtration, and endures many cleaning cycles.
