Products Clarity™ Cartridges & Capsules Small-Volume Pleated Cartridges

BRS - Brevi-MAXX Polysulfone Membrane

Strainrite's Brevi-MAXX series of pleated filter cartridges offer a compact-size cartridge filter for smaller applications. Nearly all of our standard cartridge filter media, including membranes (PES polyethersulfone membrane, charged nylon, PTFE membrane and more) and pre-filtration materials (including polypropylene and glass fiber) can be placed into this 2.25" diameter configuration. This is an ideal format for smaller batches, lower flow rates, and smaller footprint compared to other traditional cartridges.

Product Overview

The Brevi-MAXX BRS cartridge places polysulfone membrane media in a compact 2.25-inch-diameter configuration. With retention ratings from 0.05 to 1.2 µm, BRS gives process
users a space-efficient membrane option for fine liquid filtration where polysulfone media are specified.

Its small format is designed to reduce product hold-up and support higher recovery of valuable fluids compared with larger cartridges. BRS is a practical choice for pilot work, small batches, point-of-use service, and OEM equipment with limited installation space.
