Memtrex MP-B

Summary

Product identification

Memtrex MP-B (MMP-B) filters are pleated filters with a hydrophilic polyethersulfone membrane, specifically designed for beverage applications. They exhibit low protein-binding, high flow rates, and high throughputs. Every filter is 100% integrity tested.

Typical applications include final filtration of:

• Wine
• Beer
• Fruit Juices
• Bottled Water

Memtrex MP-B filters are available in the following absolute pore size micron ratings: 0.2, 0.45, and 0.65 µm.

Materials of Construction

• Membrane: Hydrophilic Polyethersulfone
• Prefiltration Media: Polypropylene Microfiber
• Support Layers: Polypropylene Microfiber
• Core and Cage: Polypropylene
• Endcaps and Adapters: Polypropylene

Mechanical / hydraulic

• Nominal O.D: 2.75” (70mm)
• Nominal I.D: 1.25” (31mm)
• Effective Filtration Area: 6.6ft² (0.62m²)

Operational Limits

• Maximum Forward Differential Pressure: 60 psi (4.1 bar) @ 70°F (21°C)
• Maximum Reverse Differential Pressure: 30 psi (2.1 bar) @ 70°F (21°C)
• Maximum Operating Temperature: 180°F (82°C) at 10 psid (0.7 bar) in water

Integrity Testing

(Air diffusion per 10” module after saturation with clean water)

• 0.2 µm: ≤ 19 cc/min at 30 psi (2.07 bar)
• 0.45 µm: ≤ 16 cc/min at 20 psi (1.38 bar)
• 0.65 µm: ≤ 12 cc/min at 13 psi (0.90 bar)

Flow Performance

The provided text indicates a table for flow performance in clean water but does not contain the data itself. See the official PDF for exact tabulated values.

Sterilization and Chemical Compatibility

Memtrex MP-B filters may be autoclaved or in situ steam sterilized (up to 257°F [125°C] 30-minute cycles) for a maximum accumulated exposure of 10 hours. Alternatively, the filters may be sanitized with compatible chemical agents. Filter cartridges are designed for resistance to a wide range of chemical solutions, but users should verify chemical compatibility for each application.

Certifications and Compliance

• Materials meet US FDA requirements for food contact under applicable regulations in 21 CFR.
• Meet the test criteria for USP Class VI-121°C Plastics.
• Aqueous extracts from Memtrex MP-B filters contain less than 0.25 EU/ml.
• The filters typically exhibit low levels of non-volatile residues.

Ordering Information

Ordering information is provided in a coded format, allowing selection of:
