Data sheet Prefiltration or clarification felt bag, assuring economical nominal filtration. QUALIPOCHE F bags are made from fibers that allow for decreasing porosity. The needle felt gives the bag a good retention capacity with minimal pressure drop. The surface of the felt retains coarse impurities and its internal structure ensures retention of finer particles. The wide range of filter materials offers excellent chemical compatibility for a variety of industrial applications. The bags are also available in a thicker version (PP and Polyester) which significantly increases performance and service life. Characteristics & benefits • Porosity wide range from 1 to 200 µm. • Standard or custom bag. • W shaped bag available enabling a 60% increase in filtration area. • Wide range of filtration media : polypropylene (PP), polyester (PES), Nylon, polytetrafluoroethylene (PTFE). • Thick felt design available for increased retention capacity and life span : PP and PES. • External surface with thermal treatment to prevent leaching. • Woven handle on the bags with retaining ring for a better grip. • Complies with EU 1935/2004, EU 10/2011 and its amendments, EU 2023/2006 and complies with FDA regulations according to 21 CFR parts 177-1520 and 176-170 (in IW code). • Molded rings complete with integral lifting handles. • Made from silicone-free materials. • Lot number on bags and packaging.
