Data Sheet: GORE® LOW DRAG FILTER BAG 8378 PTFE Felt 830 g/m² (24.5 oz/yd2)
Data Sheets, United States
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
- GORE® LOW DRAG Filter Membrane technology provides an excellent combination of filtration efficiency, airflow, and durability compared to other industry leading membranes.
- Potential benefits of this new technology are longer bag life, higher product throughput or fan energy savings or some combination thereof, depending on the application.
- Woven ePTFE scrim for outstanding dimensional stability, extended flex life, and resistance to mechanical damage. All PTFE construction provides highest allaround chemical resistance and maximum bag life.
Applications
- Chemicals Processing: Chemical process reactors that incorporate micronizing, drying, grinding, and product collection in extreme environments that are chemically and thermally aggressive.
- Minerals 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.
