Memtrex HFE

Summary

Product identification

• Product Name: Memtrex HFE - Halar PTFE
• Description: All fluoropolymer pleated cartridge filter, made entirely from fluoropolymer materials, including Halar (ECTFE) and PTFE.
• Features: Edge lamination technology for lower pressure drop and increased flow rate, broad chemical compatibility, consistent and uniform process streams, high flow rates, high purity results, and absolute rated efficiencies (99.9% filtration efficiency at rated pore size based on ASTM F795 and F661 test methods).
• Manufacturing Environment: Manufactured and packaged in a cleanroom environment.
• Absolute Pore Size Micron Ratings: 0.05, 0.1, 0.2, 0.45, and 1 µm.
• Typical Applications:
  • Chemicals
  • Microelectronics
  • Pharmaceuticals

Mechanical / hydraulic

• Materials of Construction:
  • Core and Cage: Halar (ECTFE)
  • Support Layer: Halar (ECTFE)
  • Membrane: ePTFE
  • End caps: Halar (ECTFE)
• Nominal Dimensions (for models MHFE85, MHFE91, MHFE92, MHFE94, MHFE01):
  • Nominal O.D.: 2.75” (70mm)
  • Nominal I.D.: 1.25” (31mm)

Product water

• Integrity Testing (Test Pressure):
  • 0.05 µm: ≤ 5 cc / min at 40 psig (2.76 bar)
  • 0.1 µm: ≤ 5 cc / min at 40 psig (2.76 bar)
  • 0.2 µm: ≤ 5 cc / min at 30 psig (2.07 bar)
  • 0.45 µm: ≤ 5 cc / min at 20 psig (1.38 bar)
  • 1 µm: ≤ 5 cc / min at 15 psig (1.38 bar)
• Extractables: Aqueous extracts from Memtrex HFE filters contain less than 0.25 EU/ml. The filters typically exhibit low levels of non-volatile residues.
• Certifications:
  • Meets U.S. FDA requirements for food contact under the applicable regulations in 21 CFR.
  • Meets the test criteria for USP class VI-121°C Plastics.

Flow performance

Flow performance data in clean water is based on a 10” length filter. See the official PDF for exact tabulated values.

Additional information

• Sanitization: Memtrex HFE filters may be sanitized with compatible chemical agents. The filters must not be autoclaved or steam sterilized.
• Chemical Compatibility: Veolia filter cartridges are designed and manufactured for resistance to a wide range of chemical solutions. Conditions will vary with each application, and users should carefully verify chemical compatibility.
