Features and 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).
  • Carbon-filled poly-acrylonitrile copolymer fibers provide static dissipation (passes NFPA-99 Static Decay Test).
  • Available in top, bottom, and horizontal loading configurations. Withstands pressure drop up to 6.2 kPa (25 inches water gauge).
  • 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 pigment, plastic, and catalyst industries.
  • Minerals Processing: Coal mill collectors, finish mills, raw mills, bulk pneumatic conveying, and bin vent dust collectors.
  • Metals Processing: Process venting and material handling dust collectors for pulverized coal.
  • Power Generation and Incineration: Material handling for coal and limestone.
