Memtrex NY

Summary

Product Identification

Memtrex NY (MNY) filters are uniquely constructed for superior performance with a serial membrane layer design that incorporates a large pore-size membrane layer upstream of the final membrane layer. The first membrane acts as a prefilter to increase the life and efficiency of the cartridge and is highly effective in retaining difficult contaminants such as gelatinous particles. The final membrane layer ensures consistent retention characteristics.

Veolia’s Nylon 66 membranes are naturally hydrophilic, non-shedding, and do not contain leachable wetting agents. Thermoplastic sealing technologies are used in the cartridge construction, eliminating the need for potentially contaminating adhesives. Each cartridge is manufactured under strict production control and is individually integrity tested.

MNY filters are available in the following absolute pore size micron ratings: 0.1, 0.2, 0.45, 0.65, and 1.0 µm.

Materials of Construction:

• Media: 2 layers of Nylon 66 Membrane (prefilter layer over final layer)
• Support Layers: Polyester Microfiber
• Core and Cage: Polypropylene
• Endcaps and Adapters: Polyester

Typical Applications:

MNY filters offer excellent chemical compatibility, making them suitable for a broad range of applications such as high purity water, strong solvents, photoresists, and other critical process fluid systems. Typical applications include:

• Filtration of pharmaceuticals intermediates
• Filtration of positive photoresists
• Final filtration of beverages

• 0.45 µm: ≤ 50 cc/min at 15 psig (1.03 bar)
• 0.65 µm: ≤ 50 cc/min at 12 psig (0.83 bar)
• 1.0 µm: ≤ 50 cc/min at 5 psig (0.34 bar)

Additional Information:

• Memtrex NY 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. Alternately, the filters may be sanitized with compatible chemical agents.
• The material contained in Memtrex NY pleated filters meets U.S. FDA requirements for food contact under the applicable regulations in 21 CFR.
• Memtrex NY filters meet the test criteria for USP class VI-121°C Plastics.
• Aqueous extracts from Memtrex NY filters contain less than 0.25 EU/ml.
• The filters typically exhibit low levels of non-volatile residues.
• Filter cartridges are designed and manufactured for resistance to a wide range of chemical solutions. Users should verify chemical compatibility for specific applications.
