3M™ series NB polypropylene and polyester bag filters leverage 3M™ 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. 3M™ series NB polypropylene and polyester bag filters are cost effective solutions for applications where nominally rated bag filtration is preferred. These 3M™ series NB filter bags are manufactured in size #1 and #2 configurations, ranging in grades from 1 to 200 microns and fit into standard bag filter baskets and housings. 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. Welded side seams form the bag and secure the sealing ring. Because there are no sewn holes there is no particle bypass 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. State of the art procedures are used to properly weld the seams and affix the media to the collar and form a complete, cohesive filter with no holes from sewing. Proper sealing of the bag in the filter housing is necessary for prevention of fluid bypass and subsequent contamination of the downstream fluid. All 3M™ series NB polyethylene and polyester filter bags are offered in plastic and metal ring sealing collar versions that will properly seal onto most filter bag manufacturers' housings. For plastic collar versions, the filter bag media is welded 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, etc.). For ease of identification and traceability, the handles are engraved 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. Each felt filter bag grade is manufactured 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 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.
