  • Inside-Outside Flow Configuration, effectively captures contaminants on the inside

  • Low unit-cost bags are collapsible for easy handling

  • Material has the ability to handle viscous fluids

  • Welded seams and thermally treated exterior surfaces for control of fiber migration

  • Manufacturing processes do not include the use of silicone or adhesives for greater purity of filtered media



3M™ Series NB Polypropylene & Polyester bag filters leverage 3M’s filtration experience and manufacturing expertise to provide cost effective solutions for applications where nominally rated bag filtration is appropriate. 3M Series NB bags are offered in Size #1 and #2 configurations in grades from 1 to 200 microns and fit into standard bag filter baskets and housings.


Filter bags use welded Side Seams to form the bag and secure the sealing ring. Because there are no sewn holes there is no particle by-pass through the seam. Media migration is also controlled through thermal treatment of the exterior surface, which prevents material fibers from migrating into the clean, filtered process media. Filter bag then use state-of-the-art procedures to properly weld the seams and affix the media to the collar and form a complete, cohesive filter with no holes from sewing. 


All of  3M NB series filter bags are ISO 9001:2008 certified and do not include silicone, binders, or adhesives. All polypropylene grades and specific polyester grades use materials that are listed for food contact per 21 CFR.
