EPS Grade Polyethersulfone Membrane Media Filter Cartridges
Polyethersulfone Membrane Media Filter Cartridges Developed for the Special Needs of the Electronics Industry
Product CatalogPleated Filter Cartridges
EPS cartridges are designed to meet the special needs of the electronics and high purity chemical industries. Polyethersulfone membrane cartridges are resistant to most acids and bases and capable of handling strong sanitization agents. High flow rates make Polyethersulfone a good choice for central DI systems. This membrane will also handle elevated temperatures in compatible fluids. To minimize extractables, each cartridge module is pulse, power flushed until the rinse effluent reaches 17+ Megohm-cm and less than 3 ppb TOC. Each cartridge module is also individually tested.
Note
All materials of construction are FDA accepted. Final assemblies have been validated to pass USP class 6 Toxicology extractable tests, oxidizable substances for plastics, endotoxin level and other quality tests.
Chemical Sanitization
Industry standard concentrations of hydrogen peroxide, peracetic acid, sodium hypochlorite and other selected chemicals. Sanitization protocols designed to extend the useful life of EPS cartridges are available from Critical Process Filtration, Inc.

Point of Use Filtration
Validation
EPS grade cartridges are validated using modified HIMA protocols at a challenge level of 106 organisms per cm2 of filter media. (0.22 µm challenged with Brevundimonas diminuta) (0.45 µm challenged with Serratia marcescens) (0.65 µm challenged with Saccharomyces cerevisiae).
Flow Rate
See the Flow Rate table in more image which represents typical water flow at a one psi (69 mbar) pressure differential across a single 10-inch cartridge element. The test fluid is water at ambient temperature. Extrapolation for housings with multiple elements and higher pressure drops is acceptable, but as flows increase the pressure drop of the housing becomes more apparent.
Quality Standards
Our goal is to ensure our customers the greatest possible value for their filtration dollar. We achieve both low cost manufacture and high quality by employing state of the art manufacturing equipment. This computer-controlled equipment is highly automated, reducing hand operations that compromise quality. Each operation, including assembly, testing, cleaning, drying and packaging, is done in appropriately rated clean rooms. Critical Process Filtration manages an ISO 9000 facility that produces validated products to rigorous standards. Manufacturing is controlled using sophisticated MRP software that is networked to work stations in manufacturing centers and inspection points. During the manufacturing and inspection processes, data is collected “real time” from machinery and measuring instruments. This allows variable and attribute data to be quickly and easily analyzed to facilitate constant improvements in both quality and cost.
Total Performance
Critical Process Filtration, Inc. is a vertically integrated supplier of filtration products and services to industries in which filtration is considered to be a critical part of the manufacturing process. We manufacture a complete line of products to help you achieve all your filtration requirements from a single source.
