UltraPure F&B, nylon 6,6 membrane cartridge by Exova

Description

The UltraPure F&B is a nylon 6,6 membrane filter cartridge for microbial stabilization and particle removal in the food and beverage industry. It works as a final filter or as upstream protection for final filters.

The membrane is naturally hydrophilic: it filters with high flow rates and a very low pressure drop. The 0.1 and 0.2 µm ratings retain more than 10⁷ Brevundimonas diminuta per cm², according to the FDA definition of sterilizing-grade filters, and the 0.65 µm rating, more than 10⁷ Saccharomyces cerevisiae per cm².

100 % of the cartridges are tested at the plant, and integrity is checked at origin by diffusive flow. The cartridge also has diffusive flow and bubble point integrity values so that users can repeat the test at their facility.

It withstands repeated steam sterilizations, in-line or in an autoclave, and sanitization with hot water at 80 °C and chemical cleaning and disinfection agents, so it can be reused.

Hydrophilic nylon 6,6 membrane

Naturally hydrophilic: high flow rates and a very low pressure drop, as a final filter or as upstream protection.

Declared retention by rating

0.1 and 0.2 µm: more than 10⁷/cm² of Brevundimonas diminuta. 0.45 µm: Serratia marcescens. 0.65 µm: Saccharomyces cerevisiae.

100 % integrity tested

Checked at the plant by diffusive flow, with diffusive flow and bubble point values for repeating the test at the facility.

Sterilizable and reusable

Multiple cycles of 30 to 60 minutes with steam at 121 °C, in-line or in an autoclave, and with hot water at 80 °C.

Suitable for food contact

FDA 21 CFR 177 materials, Directive 2002/72/EC, and migration testing per the Argentine Food Code and Mercosur SGT3.

Manufactured in an ISO 7 cleanroom

After manufacturing, each cartridge is rinsed with purified water to remove manufacturing extractables.

Frequently asked questions

Can it be used as a final filter for wine?

Yes. The catalog specifies it for the final filtration of wine, bottled water, and unpasteurized alcoholic beverages, and as a prefilter ahead of final filters. For yeasts, the 0.65 µm rating retains more than 10⁷ Saccharomyces cerevisiae per cm².

Can it be steam-sterilized in place?

Yes. It withstands multiple cycles of 30 to 60 minutes at 121 °C, with in-line steam or in an autoclave, and the cartridge can be reused. It is recommended only for single-open-end cartridges with internal reinforcement at the 226 or 222 O-ring fitting.

Which chemicals can be used for sanitizing and cleaning?

Peracetic acid up to 1 % (10,000 ppm) at room temperature for sanitizing, and sodium hydroxide up to 1 % (10,000 ppm) for cleaning, in multiple cycles of 30 to 60 minutes.

Can I test the integrity at my plant?

Yes. 100 % of the cartridges are tested at the factory and integrity is checked by diffusive flow; in addition, the cartridge has diffusive flow and bubble point integrity values so that users can repeat the test.

What lengths and connections are available?

A 2.75″ (70 mm) diameter and lengths of 10″, 20″, 30″, and 40″. It is offered with double 226 or 222 O-rings, with a fin or a flat end, or as double open end (DOE).
