Air filtration membrane Tetratex®

surfacemicroporous fabricPTFE

Tetratex membrane filter media is a proprietary expanded microporous PTFE (ePTFE) membrane manufactured solely by Donaldson and engineered for high performance. Tetratex membranes and laminates offer these great features and benefits: Particle Retention – Removes micro-organisms, aerosols, and small particles Increased Flow Rates and Throughput – Allows high airflow, and low-pressure drop while maintaining a consistent pore size, helping to increase filter life and reduce operating costs Reduced Shedding / Minimal Extractables – Enables compliance with stringent extractable limits Bacterial Retentive Membrane – Reduces the risk of pathogens USP Class VI Compliant – Meets both toxicity requirements and residual limits Steam Sterilization – Can be sterilized with steam or ethylene oxide for food, beverage, and pharmaceutical applications Chemically Resistant – Provides excellent chemical resistance in a variety of applications that involve challenging process conditions Inherently Hydrophobic – Demonstrates excellent water repellency With pore sizes ranging from 0.05 to 5 microns, Tetratex ePTFE membrane can be converted into pleated cartridges, capsules, inline filters, and disks and is also available thermo-bonded to a variety of substrates. Applications Membrane Solutions for Every Challenge Tetratex membrane filter media can be further tailored to meet your stringent membrane requirements across our wide-ranging areas of application expertise, including: Chemicals Power generation Metals Minerals Food & beverage Pharmaceuticals Fuel cells Life sciences Medical devices
