Industry’s Filtration Partner
PTFE Membrane Media Filter Cartridges Engineered and Manufactured for Cost Effective Filtration

GTM grade PTFE cartridges are designed for general purpose use wherever a cost effective PTFE membrane filter is required. Manufactured with inherently hydrophobic PTFE membrane, these cartridges are designed for use in the filtration of aggressive solvents, and as compressed gas and vent filters. These cartridges are found in the manufacturing processes of pharmaceutical companies, semi-conductor manufacturers and bulk chemical companies. The cartridge surface area, filter core design, pleat configuration and pleat packing density have been optimized to provide increased cartridge life resulting in lower filtration operating costs. Each cartridge module is integrity tested.

Applications

N/A Final Filtration of:

  • Compressed Air
  • Solvents
  • Pressurized Gases
  • Tank Ventilation

Flow Rate

N/A See the Flow Rate table in more image which represents typical water flow and air flow rates. These values are approximations because of the differences in pressure drop encountered in housings and piping systems. Extrapolation to multiple length cartridges in multi-round housings can be done for sizing purposes. Exact flow rates will be installation dependent.

Quality Standards

N/A Our goal is to ensure our customers the greatest possible value for their filtration dollar. We equipment is highly automated, reducing hand operations that achieve both low cost manufacture and high quality by employing state of the art manufacturing equipment. This computer controlled 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.
