3M Series NB

3M™ Series NB Filter Bags

3M Purification’s filter bag offering includes polypropylene and polyester felt and nylon monofilament materials in a wide range of grades (removal ratings).
Not all liquid bag filters are created alike.
3M Purification designed and manufactured bag filters offer following important features.
For some liquid bag applications, the use of nylon monofilament (NMO) materials represents a better option than conventional felt materials.

Features / Benefits (Polypropylene, polyester)

• Predictable performance for desired filter effluent quality
• Manufacturing processes do not use silicone or adhesives
• Control of fluid bypass through proper sealing into most filter bag manufacturer’s housings
• Ergonomically designed handle for ease of bag removal
• Grade and lot information etched on collar for identification and traceability
• Welded side seams and thermal treated exterior surfaces
• Control of fibre migration and subsequent downstream fluid contamination
• Approved for food contact use (PPS Elements only)

Features / Benefits (Nylon monofilament)

• Allows desired undersized particles to pass through (metallic paints…)
• Effective removal of oversized contaminants
• High fibre strength reducing the likelihood of bag rupture and downstream fluid contamination
• Appropriate choice for filtration of high temperature cleaning solutions
• Cost effective filtration solution for those applications requiring removal of coarse particles only
