LifePure Plus F&B, extended-area PES membrane cartridge by Exova

Description

The LifePure Plus F&B is an asymmetric polyethersulfone (PES) membrane final filter cartridge. It microbially stabilizes the beverage before it enters the filler.

The membrane has open pores on the outer face that narrow down to the final pore of the filter. With its extended filtration area of 8,000 cm² per 10″, it allows high flow rates with low pressure drop and has a high contaminant retention capacity. There are six ratings, from 0.1 to 1.2 µm.

100 % of the cartridges are integrity tested at the plant, and the model has diffusive flow and bubble point integrity values so that the end user can also test it. It withstands sanitization with hot water at 80 °C and with chemicals, as well as multiple steam sterilizations, so the cartridge can be reused.

8,000 cm² per 10″

Extended filtration area with an asymmetric membrane: high flow rates, low pressure drop, and high retention.

Final filter before the filler

Frequently asked questions

Where is it installed in the packaging line?

As a final filter, before the beverage enters the filler, to microbially stabilize it.

Can the integrity be tested at the user's plant?

Yes. In addition to the testing of 100 % of the cartridges at the factory, the model has diffusive flow and bubble point integrity values so that the end user can test it.

What filtration area does it have?

8,000 cm² per 10″, in 10″, 20″, 30″, and 40″ cartridges with a 2.75″ (70 mm) diameter.

How is it sterilized?

With steam in-line or in an autoclave: multiple cycles of 30 to 60 minutes at 121 °C without loss of integrity. Only in single-open-end configurations (B to E).
