Features & Benefits

  • Patented GORE High Durability membrane technology provides an excellent combination of filtration efficiency, airflow, and durability.
  • Polyester fibers provide good all-around chemical resistance, especially in applications operated below 79 °C (175 °F).
  • Special multifilament scrim design provides excellent dimensional stability and resistance to mechanical damage over the life of the filter


  • Chemicals Processing: Dryers, bin vents, and nuisance dust collectors in the pigment, plastic, and catalyst industries.
  • Minerals Processing: Finish mills, raw mills, bulk pneumatic conveying, and bin vent dust collectors.
  • Metals Processing: Process venting dust collectors in the lead, lead oxide, and iron and steel industries. Pulverized coal injection systems, fume and bulk handling systems in coke production, and sand reclamation systems in foundries.
  • Power Generation and Incineration: Material handling for coal and limestone
