Pleated Cartridge Filters

Pleated cartridge filters use large-area pleated construction — wrapping membrane media in V-pleat or star-pleat geometry around a support core — to deliver 5–10× the effective filtration area of comparably-sized melt-blown or string-wound cartridges, dramatically reducing initial pressure drop and extending service life. JIUNYUAN pleated cartridges cover PES, PTFE, PVDF, PP, Nylon66, UPE, Polysulfone and Glass Fiber media in a full retention range from 0.03μm nano-class to 10μm.

Media selection follows the target fluid: hydrophilic PES/PVDF for aqueous and general chemical point-of-use filtration; hydrophobic PTFE for sterile gas/air filtration and aggressive chemicals; UPE and Nylon66 as the standard solution for semiconductor wet etch, CMP, and photoresist filtration. All Semi-Grade cartridges are assembled in Class 100 environments and qualified by full extractables, metallic-ion release (ICP-MS) and particle-shedding tests.

Typical applications: semiconductor wet processes (SC-1/SC-2, TMAH, HF, IPA), pharmaceutical sterile filtration (0.2μm/0.22μm bioburden reduction), biotech mAb/vaccine final filtration, chemical solvent clarification, food & beverage sterile bottling, and UPW / DI Water POU loops.
