Polypropylene Membrane Media Filter Cartridges Engineered and Manufactured for Cost Effective Filtration

GPM grade Polypropylene Membrane cartridges are designed for general purpose use wherever a cost effective membrane filter is required. Designed to hold the maximum amount of filter media that can be completely and effectively utilized in a cartridge, GPM filters lower the cost of filtration . GPM cartridges are flushed with 17+ megohm-cm water to remove potential extraneous manufacturing debris. These cartridge modules are also individually tested for integrity. Priced below special purpose cartridges, GPM cartridges are still manufactured with the same careful attention to both quality and performance. Often used in place of PTFE Membrane because of lower cost and no undesirable extractables

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.
