3M™ NB Series Filter Bag, 3M
Filters Liquid Process Filters
3M™ Series NB PP and PE bag filters leverage 3M’s filtration experience and manufacturing expertise to provide cost effective solutions for applications where nominally rated bag filtration is appropriate.

  • 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

We provide cost effective solutions for applications where nominally rated bag filtration is preferred.

3M Series NB bags are offered in Size #1 and #2 configurations in grades from 1 to 200 µm and fit into standard bag filter baskets and housings. Our lightweight, low cost filtering material offers high chemical and corrosion resistance. It has a high contaminant holding capacity and ability to remove both solid and viscous particles.

We 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. We 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.

Plastic or metal ring seal

For plastic collar versions, we weld the filter bag media to a specially designed plastic collar to provide proper sealing of the 3M NB series filter bags in most conventional bag housings. The plastic collar incorporates an ergonomically designed handle allowing for easy removal of the filter bag from the filter housing. Handle designs also allow for insertion of bag accessories (displacement balloons, magnets, and more). For ease of identification and traceability, we engrave the handles with micron grade and manufacturing lot information.
Metal ring collar versions use a galvanized steel ring for sealing the 3M NB series filter bag in the housing. These versions are appropriate for use in most filter bag housings that will not accept the plastic collar version.
Made to filter
We manufacture each felt filter bag grade from high performance fibers based on extensive media performance testing. They provide good to excellent chemical resistance to mineral acids, organic acids, alkalis, organic solvents, and micro organisms. All PP grades and specific PE grades use materials that are listed for food contact per 21 CFR.

Certifications: All of our 3M NB series filter bags are ISO 9001:2008 certified and do not include silicone, binders, or adhesives.
