This polytetrafluoroethylene coated fiberglass GORE® LOW DRAG Filter Bag is the latest technology for pulse jet style dust collectors, enabling operation in high temperature environments (260 °C, 500 °F). GORE LOW DRAG Filter Bags incorporate an entirely new class of membranes which has inherently less resistance to airflow and therefore provides a variety of benefits.

Features and Benefits

The GORE LOW DRAG Filter Bags 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 increased alternative fuel utilization. In all cases, this membrane provides excellent particulate capture efficiency, dust cake release and filtration performance, ultimately resulting in a lower total cost of ownership.

  • The PTFE coated backing material offers enhanced flex life and chemical resistance, resulting in long bag performance life.
  • 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.
