ProcessGard® PES Filters

Point-of-use, solvent, DI water, and dilute acid/base filters with high flow rate and good contaminant retention performance in microelectronic cleaning applications.

– PES cartridge and disposable filters are high-flow, longer lifetime filters ideally suited for weak acid, base, and ultrapure DI water filtration
– PP cartridge and disposable filters are ideally suited for acid, base, process water, solvent, dye, and lacquer filtration in flat panel display and chemical manufacturing
– PS high-retention filters for final cleaning and ultrapure DI water processes
– various retention ratings, fittings sizes, and types to meet various requirements
