Industry’s Filtration Partner
Polyethersulfone Membrane Media Filter Cartridges Developed for the Special Needs of the Electronics Industry

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. Tomore

Applications

N/A Final Filtration of:

  • UP DI Water
  • Acids & Bases
  • Plating Solutions
  • Etch Baths
  • Chemicals
  • Solvents
  • Process Water
  • Point of Use Filtration

Validation

N/A 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 marscecens) (0.65 µm challenged with Saccharomyces cerevisiae).

Flow Rate

N/A 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

N/A 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

N/A 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.
