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 and 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
Operating Limits
- Maximum Operational Pressure:

- ¹Varies with connection style
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)
Compliance & Sanitization
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.
Veolia Water Technologies certifies that the materials contained in Memtrex FE Capsule filters meet U.S. FDA requirements for food contact under the applicable regulations in 21 CFR. Memtrex FE filters meet the test criteria for USP class VI-121°C Plastics.
