Features
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.
