Overview:
Our company can supple all kinds of PPS non woven bag filters.
Our company PPS filters bags are sewn with 3 - needle chain stitch to ensure seam exacting. Top constructions consist of ring top, flange top, snap band, gasket, hem, button or raw edge. Bottom removal bags are constructed with a raw top or soft cuff. Top and bottom removal bag bottoms have disc bottoms that can be sewn using a lock stitch. We can also provide wear reinforcement or custom skirts to the bottom portion of the bag to prevent premature wear from bag-to-bag and bag-to-cage abrasion

Oxidising Agents fair

PPS is degraded by strong oxidizing agents such as O2 NOX, SOX, Br2.The recommended operating temperatures stated above are for environments which do not include these oxidizing agents. The inclusion of these oxidizing agents in the operating environment in elevated concentrations lowers the recommended operating temperature below that stated above. The inclusion of the PTEF scrim can extend life of the media in those extreme chemical conditions.
