Hydrophilic High-Purity PTFE Filters Improve Flow


W. L. Gore & Associates (Gore)’s hydrophilic polytetrafluoroethylene (PTFE) filters can be used as drop-in replacements for existing filters to achieve flow improvements while maintaining or even increasing particle retention. The increase in performance can improve retention while maintaining system flow, reduce processing time, or decrease the number of filters required for a lower total cost of ownership.

The new filters incorporate the company’s proprietary high-flow hydrophilic PTFE filtration media, which does not require isopropyl alcohol pre-wetting and completely eliminates de-wetting issues in most applications. They are well suited to filtration of aqueous and high-surface-tension liquids, especially where outgassing or bubbles are a concern.
