SENTINEL and SNAP-RING monofilament filter bags feature a wide range of retention ratings. The different materials cover many applications with demanding chemical and thermal properties. These filter bags are designed for surface filtration to retain particles that are larger than the respective pore size.



  • Non-deformable monofilament material is woven into a specific pattern with fusion-welded intersections for extra strength and a retention rating
  • All nylon monofilament filter bags with the SENTINEL seal ring have an inseam for safe filtration
  • All nylon monofilament grades <125 μm are manufactured with a twill-tape envelope on the side seam and bottom seam to prevent liquid bypass through the needle holes
  • The pressure-activated SENTINEL seal ring provides a flexible, chemically resistant seal which adapts to any bag filter housing
  • Eaton strongly recommends the use of an insertion tool that facilitates the insertion of the filter bag into the bag filter housing and ensures the correct alignment of the filter bag inside the restrainer basket
