Products Clarity™ Cartridges & Capsules Small-Volume Pleated Cartridges

BRT - Brevi-MAXX PTFE 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 BRT cartridge provides PTFE membrane media in a compact 2.25-inch-diameter pleated cartridge.
Available in 0.1 and 0.2 µm ratings, BRT is intended for fine-filtration applications in which PTFE membrane media are specified.
The cartridge’s small size supports pilot-scale, point-of-use, and OEM installations while helping reduce system hold-up. Multiple lengths, endcaps, and seal materials allow the configuration to be matched to the housing and process requirements.
