Filtration

Polytetrafluoroethylene Felt, Heavy Duty, 880 g/m2 (26 oz/yd2)

Filtration

Description

A 260°C (500°F) maximum service temperature, expanded polytetrafluoroethylene felt filter bag for use in pulse jet style dust collectors with chemically aggressive operating conditions.


Features and Benefits

  • Patented GORE™ High Durability membrane technology provides an excellent combination of filtration efficiency, airflow, and durability.
  • Chemically inert providing the highest allaround chemical resistance and maximum bag life.
  • Constructed using a woven RASTEX® scrim that provides excellent dimensional stability, extended flex life, and resistance to mechanical damage over the life of the filter.

Applications

  • Chemicals Processing: Chemical process reactors that incorporate micronizing, grinding, and product collection in extreme environments that are chemically and thermally aggressive.
  • Metals Processing: Brick kilns.
  • Metals Industry: Lead, copper, and other base metal production.
  • Power Generation and Incineration: Medical and municipal waste incineration, as well as coal fired boilers.
