GORE LOW DRAG Filter Bags incorporate an entirely new class of membranes that acts as a true surface filter in fume and fine powder applications. The membrane provides excellent particulate capture efficiency, dust cake release and filtration performance. It can be operated at a lower differential pressure (dP), resulting in fan energy savings, longer bag life and improved process control.

A producer of cement in Mexico was looking to consistently meet maximum kiln feed. The plant selected GORE^® LOW DRAG Filter Bags to replace its existing membrane filters. The bags’ new membrane promotes increased airflow through the baghouse with persistently low differential pressure.

Cement producers need filtration solutions that meet both their productivity goals and their bottom line. When a cement plan in Canada looked for ways to improve operations in its pulse-jet baghouse, they found a simple solution that didn’t require adding more modules to the baghouse.

Read the following case study to learn how GORE® LOW DRAG Filter Bags make the difference in the production of TiO2 by helping you to reduce the need for offline cleaning while improving your production efficiency at the same time.

Consistent 1.2" H₂O differential pressure has been maintained since installation of GORE membrane filter bags despite a 9" H₂O excursion due to pulse-system failure. There has been no noticeable dust on the clean side of the tube sheet since installation. The first set of bags lasted three years.

Secondary after-filter blinding was eliminated. GORE membrane filter bags were cost justified in less than one month. Bag life was expected to approach two years. Customer quickly converted all SAN and ABS dryer systems to GORE membrane filter bags. Customer increased profits substantially in these areas.

Airflow increased by 10%. Production rated increased. Lower operating DP 1-2". Improved cake release eliminated product discoloration and product contamination. Bags attained 5+ years of service.

Lower operating DP (5"-7" DP) improved cake release, allowing increased airflow through collector. Bleed-through stopped, allowing capture of product. First set of bags lasted more than five years.

Results showed no visible emissions, excellent and consistent product yield, and secondary filter blinding significantly reduced. No bag failures since installation.

Solution involved installing GORE Fabric Filter Bags. Results were sixty months of continuous, problem-free service, with excellent pressure differential.
