PP Pleated Filter Cartridge, 0.55 m² (CAT#: STEM-BC-2950-ZJF)

This polypropylene pleated cartridge is designed for filtration across electronic, pharmaceutical, food, chemical, and water-treatment applications. It uses polypropylene microfiber membrane with compatible polypropylene support and flow-distribution layers. The pleated structure provides at least 0.55 m² of effective area in the stated configuration. Welding and edge sealing form the cartridge without adhesives. The construction is designed to prevent media shedding during liquid or gas service. Imported hydrophilic, imported standard, domestic high-performance, and standard domestic membranes can be selected. Different manufacturing grades support varying cleanliness, rinsing, and retention requirements. The cartridge is compatible with many acids, alkalis, alcohols, ketones, dimethylformamide, phenol, and other suitable chemicals. Every completed unit is integrity tested.
