Sure-Weld

The Sure-Weld Felt Filter Bag, with Strainrite’s proprietary “TRI-SEAL” poly flange provides a distinct advantage compared to conventional sewn filter bag with metal snap rings or industry standard poly flanges. Using state-of-the-art welding technology specifically designed to bond needle punched textile fabrics, Strainrite can offer the strongest most reliable welded filter bags on the market. Strainrite’s Sure-Weld filters come with the security of an overlap side seam, which eliminates the “bump” that occurs with conventional sewn snap ring filters. By welding to a “TRI-SEAL” poly flange Strainrite’s fully welded filter bags offer unparalleled seal security, which delivers superior filtrate consistency.
