ProFlow Protec, absolute dual-layer polypropylene cartridge by Exova

Description

The ProFlow Protec is an absolute-rated pleated polypropylene filter cartridge made with progressive-porosity polypropylene microfibers to retain particles in fluids with a high contaminant load.

The Protec version has a dual-layer medium: a prefilter layer and a final layer in the same element, that is, two filtration stages in a single cartridge. With 6,000 cm² of filtration area per 10″, it starts with a higher clean pressure drop but takes more time and more processed volume to reach the change-out differential pressure.

Retention is absolute in all its ratings, from 0.2 to 10 µm. All components are polypropylene, joined by heat sealing and free of additives, surfactants, and post-treatments: broad chemical compatibility and low extractables levels.

Absolute rating from 0.2 to 10 µm

Eight ratings: 0.2, 0.4, 0.6, 0.8, 1.2, 2.5, 5, and 10 µm, in lengths of 10, 20, 30, and 40″.

Two stages in one cartridge

Polypropylene prefilter layer and final layer in the same filter element.

Longer time to change-out

Starts with a higher clean pressure drop but reaches the change-out pressure after more time and more processed volume.

100 % polypropylene

Heat-sealed, with no additives, surfactants, or post-treatments. Broad chemical compatibility and low extractables.

Steam sterilizable at 121 °C

Multiple 30 to 60 min cycles. Also sanitizable with water at 80 °C and with chemicals up to 1 %.

Suitable for food contact

FDA 21 CFR 177 materials and non-toxic components according to the Argentine Food Code migration test.

Frequently asked questions

Is the rating absolute in all grades?

Yes. The catalog states an absolute rating in the 0.2 to 10 µm grades: 0.2, 0.4, 0.6, 0.8, 1.2, 2.5, 5, and 10 µm.

What does the dual layer provide?

It combines two filtration stages in a single cartridge: a prefilter layer and a final layer, both polypropylene. The cartridge starts with a higher clean pressure drop but takes more time and more processed volume to reach the change-out differential pressure.

Can it be steam sterilized?

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

At what differential pressure should it be changed out?

At a maximum differential pressure of 2 bar. The cartridge withstands up to 5.5 bar (80 psi) at 25 °C in the forward direction and 0.69 bar (10 psi) at 25 °C in reverse flow.

Can it be used for gases?

Yes. The catalog lists it for compressed gases and vents, as well as water, reverse osmosis pretreatment, prefiltration ahead of final filters, beverages, wine, chemicals, solvents, and cosmetics.
