We designed 3M™ LifeASSURE™ PSN Series Filter Cartridges with highly retentive nylon membrane to meet the exacting requirements of photoresist and ancillary chemical applications. Utilizing 3M Advanced Pleat Technology (APT), 3M™ LifeASSURE™ PSN series nylon filter cartridges provide maximum flow rates with minimal pressure drop, maximizing throughput and lowering cost of ownership.
3M™ LifeASSURE™ PSN Series Filter Cartridges are highly retentive nylon membrane filter elements, utilizing 3M’s Advanced Pleat Technology (APT). 3M™ LifeASSURE PSN Series Filter Cartridges provide maximum flow rates with minimal pressure drop, maximizing throughput and lowering cost of ownership.
The naturally hydrophilic Nylon 6,6 pleated membrane in an all high density polyethylene (HDPE) construction provides low extractable levels and superior reduction of gel and hard particles when compared to other membrane cartridges. 3M™ LifeASSURE™ PSN series filter cartridges are ideally suited for photoresist and ancillary chemical applications where high efficiency contaminant reduction at 0.04 μm, 0.1 μm or 0.2 μm is required.
Advanced Pleat Technology Provides Maximum Gel Reduction
A small amount of gel particles can normally be found in photoresists, which can form during manufacturing and storage. Reducing gels from photoresists is highly dependent on differential pressure across the filtration system. Since these gels are deformable, they can extrude through a filter at high differential pressures.
