Case Study: GORE® LOW DRAG Filter Bags — Longer Bag Life and Stable Operation in Refining Catalyst Production


A multinational producer of alumina catalyst desired longer pulse jet filter bag life and steadier operation in their dryer bag house. The customer historically had used Standard GORE® Filter Bags (ePTFE membrane on 543 gsm non-woven polyester backer). For this trial, they installed GORE LOW DRAG Filter Bags on an identical backer. Process data from the Standard membrane bag was used as a control comparator.
