Data Sheet: PTFE Felt Filter Bag 830 g/m2 (24.5 oz/yd2)
Data Sheets, United States
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.
