Data Sheet: Aramid Felt, Acid-Resistant GORE® Filter Cartridge 475 g/m2 (14 oz/yd2)

English

A 204°C (400°F) maximum service temperature, stayed-Aramid felt filter cartridge for use in pulse-jet style dust collectors, where high differential pressure and high cleaning pressures are required due to aggressive dust loading.


Features and Benefits

  • GORE™ membrane technology provides an excellent combination of filtration efficiency and dust cake release.
  • Polytetrafluoroethylene scrim offers superior chemical resistance and excellent dimensional stability.
  • Unique acid-resistant treatment reduces the detrimental effects of moisture and acids.
  • Withstands pressure drop up to 6.2 kPa (25 inches water gauge).
  • Available in top, bottom, and horizontal loading configurations.

Applications

  • Chemicals processing: Dryers, bin vents, and nuisance dust collectors in the pigment, plastic and catalyst industries.
  • Minerals processing: Clinker coolers.
  • Metals processing: Process venting dust collectors for base metal kiln applications.
