HL Extended Life filter bag provides superior filtration performance for removing gels, irregular shaped particles in liquid streams with a wide particle size distribution, as well as up to twice the dirt holding capacity of a standard filter bag. The bag is made of extended-file polyester and polypropylene materials utilizing a proprietary fiber blend configuration to create a media that is heavier, thicker and stronger than standard felt media, resulting in an average operational life of 2 to 4 times longer than conventional bags. The result is a dramatically higher dirt holding capacity at the same efficiency and differential pressure.
The Extended Life filter bags are specially designed with a coarse inner layer and a middle layer of felt constructed with finer fibers. The outside layer is glazed, by melting fibers together, to form a tight, secure downstream matrix, which prevents fiber migration.
Material: extended life Polyester/Polypropylene felts (PPXL, PEXL)
Micron rating: 1-200µm
Construction: w/w/w (fully welded, no by-pass)
A coarse inner layer, graded pore structure, greater depth than standard bags, providing excellent filtration performance for removing gels, irregular shaped particles
Up to twice the dirt holding capacity of a standard filter bag
Increase productivity due to longer, uninterrupted processing/run times
Reduce operating cost-savings due to fewer filter change-outs and reduced filter element disposal costs due to lower bag consumption, downtime, change-out labor, storage and disposal
The coarse, pre-filtering layer captures a large amount of contaminants without excess surface loading
Surface glazed with no fiber fall, providing higher filtration efficiency and eliminating unwanted fiber migration
Welded seam construction eliminates liquid bypass
