Woven Trade Size Filter Bags – Nylon

Ships in 4 weeks.



Our trade-size NMO woven media strainer bags (or mesh media bags) feature higher flow rates and superior dirt release compared to felt media. Their superior dirt release allows them to be washed and reused numerous times. It also makes them a smart choice for surface retention filtration.

  • Economical removal of non-deformable contaminates
  • Less susceptible to fiber release or media migration
  • Sewn seams standard (contact us for welded collars on bags with flanges)
  • No minimum order quantity

We also offer woven NMO or PEMU mesh bags in higher micron ratings up to 600 µm.
