Nylon Monofilament Filter Bag (NMO Series)
Precision woven nylon mesh filter bags, 1–1200 μm, washable and reusable.
Product Introduction
The NMO series nylon monofilament filter bag is engineered for high-precision, high-flow liquid filtration. Woven from premium nylon monofilament, the mesh has a structurally stable fixed aperture — uniform square openings that deliver accurate, repeatable filtration ratings with true surface retention and no particle bypass.
Compared with needle-felt bags, the non-shedding monofilament mesh withstands higher operating pressures and pressure surges, resists abrasion, and can be washed and backwashed for extended service life. Standard #1–#4 sizes with plastic flange, steel ring or drawstring collars.
Key Features
- 100% nylon monofilament woven mesh — fixed, uniform apertures
- Micron ratings from 1 μm to 1200 μm
- Precise surface filtration — no particle bypass, repeatable ratings
- High tensile strength and abrasion resistance; no fiber migration
- Washable and reusable — backwash to extend service life
- Broad chemical compatibility: alkalis, solvents, hydrocarbons, oils
- Standard sizes #1–#4; plastic flange, steel ring or drawstring collars

Choose monofilament when you need accurate, repeatable micron ratings, higher pressure tolerance, or a reusable bag you can wash and backwash. Choose needle-felt depth bags for maximum dirt-holding capacity with high-solids or viscous liquids.
Yes — the non-shedding monofilament mesh can be cleaned and backwashed, which extends service life significantly compared with felt bags.
Plastic flange tops (V-ring / E-ring), steel rings, zinc-plated rings or drawstrings — matched to standard filter vessels for a bypass-free seal.
