The Unrivaled Tetratex® Media Portfolio

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.
