The bag life improved, while baghouse down-time, maintenance costs, and stack emissions have all been drastically reduced. Bags have survived several acid upsets which would have completely destroyed the previous bags.

By removing the U Tube cooler pressure loss the plant was able to open the canopy hood dampers more. This allowed increased secondary flow from the shop. With less flow resistance through the DEC system the primary evacuation has also increased with better fume capture at the furnace.

The baghouse differential pressure decreased resulting in increased gas flow without expanding the baghouse. This was achieved even though the plant installed considerably less GORE^® Membrane Filter Bags than they had used when operating with non membrane bags. They closed the dilution air damper so that all the baghouse capacity is applied to the furnace. The frequent bag failures stopped and the inside of the baghouse is much cleaner.

Eliminated the need for sonic horns and dramatically decreased baghouse pressure drop. Gas flow increased significantly, even with fewer filter bags than had originally been used in the non membrane sytem.

Based on W. L. Gore & Associates’ best practices, the following information is intended to be used as a guide only. Relied on for decades, GORE® SKYFLEX® Aerospace Materials are approved for use in several technical orders for the Boeing KC-135 Stratotanker military aircraft.

Bag failures stopped since the GORE ePTFE membrane and the fiberglass backing material are not subject to hydrolysis and resist spark damage. The bags have not required tensioning since start up. Furnace suction and shop evacuation have improved due to the more consistent operation of the baghouse.

"Performance over time is critical. Like the FieldFox Handheld RF and Microwave Analyzer, key components used with it, such as microwave/RF cable assemblies, should undergo rigorous environmental testing for the variety of demanding environments they may experience."

With the new high temperature membrane filter media, required dilution air from the canopy hood is reduced and furnace suction pressure is consistently maintained, reducing furnace fugitive emissions.
