Sewn Steel Ring Filter Bag Series
The Sewn Ring Filter Bag Series from CMI provides a cost-effective solution for general industrial liquid filtration.
These bags are constructed using silicone-free needle felt or NMO monofilament mesh, and stitched with heavy-duty industrial sewing thread to ensure consistent performance in everyday filtration applications.
A steel ring (standard) or stainless-steel ring (for corrosive fluids) is sewn into the top of the bag to maintain dimensional stability and provide reliable sealing in most standard bag filter housings.
Available in a wide range of materials and micron ratings, sewn ring bags remain the most commonly used filter bags across various industries.
