Data Sheet: GORE® LOW DRAG Filter Bags 3170, Fiberglass Fabric, 339 g / m2 (10 oz / yd2)


This long lasting, acid-resistant fiberglass fabric filter bag is the latest technology for reverse air style dust collectors, enabling operation in high temperature environments (260 °C, 500 °F).  It comes with our new GORE LOW DRAG Membrane which has  inherently less resistance to airflow and therefore provides a variety of benefits.


Features and Benefits

  • The GORE LOW DRAG Membrane can be operated at a lower differential pressure (dP), resulting in fan energy savings, longer bag life and improved process control. Some customers choose to operate at a higher airflow (same dP) resulting in potential increases in production capacity or more effective evacuation. In all cases, this membrane provides excellent particulate capture efficiency, dust cake release and filtration performance.
  • The acid-resistant backing material offers enhanced flex life and chemical resistance, resulting in long bag performance life.
  • RASTEX® high tenacity sewing thread means a more rugged, dependable construction.
  • Optimized filter bag design brings the best properties of the filter materials together into a finished product where the strength of the design matches and enhances the durability of the components.


  • Chemicals Industry: Carbon black.
  • Energy Production: Utility and Industrial coal-fired boilers.
  • Metals Industry: Iron, steel and ferro-alloy furnaces.
  • Minerals Industry: Cement and lime kilns.
