Summary

Product identification

Memtrex HFE-T filters feature an ePTFE membrane edge-laminated on Halar (ECTFE), with polyester plastic parts. They are pleated filters with PTFE membrane.

Available absolute pore size micron ratings:

• 0.05 µm
• 0.1 µm
• 0.2 µm
• 0.45 µm
• 1 µm

Materials of Construction

• Core and Cage: Polyester
• Support Layer: Halar (ECTFE)
• Membrane: ePTFE
• End Caps: Polyester

Mechanical / hydraulic

Dimensions

The nominal O.D. for all listed filter models is 2.75” (70 mm) and the nominal I.D. is 1.25” (31 mm). See the official PDF for exact tabulated filter models.

Operating limits

• Maximum Forward Differential Pressure: 60 psi (4.14 bar) at 70°F (21.1°C)
• Maximum Reverse Differential Pressure: 30 psi (2.07 bar) at 70°F (21.1°C)
• Maximum Operating Temperature: 205ºF (96.1ºC) at 25 psid (1.7 bar)

Flow performance

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

Integrity Testing

• 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)

Certifications and Compliance

• Memtrex HFE-T pleated filters meet U.S. FDA requirements for food contact under applicable regulations in 21 CFR.
• Meet the test criteria for USP Class VI-121°C Plastics.
• Aqueous extracts contain less than 0.25 EU/ml.
• Typically exhibit low levels of non-volatile residues.

Applications

Memtrex HFE-T filters are suitable for very harsh chemical environments. They are manufactured and packaged in a cleanroom environment.

Typical applications include:

• Chemicals
• Microelectronics
• Pharmaceuticals

Additional Information

Filters may be sanitized with compatible chemical agents but must not be autoclaved or steam sterilized. Users should carefully verify chemical compatibility for each application.
