Data Sheet: PTFE Felt Filter Bag 830 g/m2 (24.5 oz/yd2)

English

A 260 °C (500 °F) maximum service temperature, 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 all-around chemical resistance and maximum bag life.
  • Constructed using a woven PTFE 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.
  • Minerals processing: Brick kilns.
  • Metals processing: Lead, copper, and other base metal production.
  • Power generation and Incineration: Medical and municipal waste incineration, as well as coal-fired boilers.
