Memtrex FE CMFE capsules

Summary

Product identification

Memtrex FE (CMFE) capsule filters consistently achieve absolute filtration with low extractables. They are constructed using a 100% PTFE membrane and designed for reliable general chemical and air filtration.

Typical Applications:

• Acids, base, and oxidant filtration
• Bulk chemical filtration
• Sterile venting
• Electronics grade chemical filtration
• Process air and gas filtration

Features and Benefits:

• Ideal for aggressive chemicals, air, process gas filtration, and vent uses
• Highly hydrophobic membranes with low extractables
• Individually integrity tested during manufacturing

Available Absolute Micron Ratings:

• 0.1 µm
• 0.2 µm
• 0.45 µm
• 1.0 µm

Materials of Construction:

• Filtration Media: Hydrophobic Teflon (PTFE) Membrane
• Membrane Support Layers: Polypropylene Microfiber
• Structural Components: Polypropylene

Mechanical / hydraulic

Dimensions:

• Diameter: 3.5” (9 cm)
• Capsule Size / Effective Filtration Area / Length (varies with connection style):
  • Small: 0.8 ft² (748 cm²), 3.5–5.0” (9–13 cm)
  • Medium: 3.0 ft² (2806 cm²), 7.6-9.1” (19-23 cm)
  • Large: 5.9 ft² (5500 cm²), 11.5-13.0” (29-33 cm)

Integrity Testing:

• Water intrusion is < 1.8 cc/min per ft² of effective filtration area.
• Micron Rating / Test Pressure:
  • 0.1 µm: 40 psi (2.8 bar)
  • 0.2 µm: 30 psi (2.1 bar)
  • 0.45 µm: 20 psi (1.4 bar)
  • 1.0 µm: 5 psi (0.3 bar)

Flow Rate Performance: Flow rate performance test data for small, medium, and large Memtrex FE Capsule Filters (using a 10-inch length filter) are detailed in figures within the official PDF. See the official PDF for exact tabulated values.

Operating limits

• Maximum Operational Pressure:
  • 80 psi (5.5 bar) @ 70°F (21°C) in Liquid
  • 55 psi (3.8 bar) @ 70°F (21°C) in Gas
• Maximum Differential Pressure: 60 psi (4.1 bar) @ 70°F (21°C)
• Maximum Operating Temperature: 110°F (43°C) at <30 psi (2.0 bar) Operating Pressure (with PTFE membrane)

Additional Information

• Memtrex FE Capsule filters may be sanitized with a variety of commonly used chemical agents.
• The capsules may be repeatedly autoclaved at 257°F (125°C) for 30 minutes at up to 5 cycles.
• The materials contained in these filters meet U.S. FDA requirements for food contact under applicable regulations in 21 CFR.
• Memtrex FE filters meet the test criteria for USP class VI-121°C Plastics.
• Veolia filter capsules are designed and manufactured for resistance to a wide range of chemical solutions. Users should carefully verify chemical compatibility for their specific application.

Connection Styles

• ¼” – ½” (6.3 – 12.7 mm) hose barb
• 3/8” (9.5 mm) hose barb
• ¼” (6.3 mm) NPT male
• ½” (12.7 mm) NPT male
• 1.5” (38.1 mm) sanitary flange
