0.22 µm PP Pleated Filter Cartridge, 0.55 m² (CAT#: STEM-BC-2978-ZJF)

This polypropylene pleated cartridge is designed for high-precision filtration of compatible liquids and gases. It uses a polypropylene microfiber membrane with polypropylene nonwoven flow-distribution layers. The pleated structure provides at least 0.55 m² of effective filtration area in the stated configuration. Edge sealing and welded end caps form the cartridge without adhesives. The integrated construction is designed to prevent filtration-media shedding. Multiple polypropylene membrane grades can be selected according to cleanliness and retention requirements. The 0.22 µm configuration supports fine particulate removal and process-fluid polishing. Every completed cartridge undergoes integrity testing before release.
