Parker Proflow™ II-E Select Cartridge

High-Performance Cartridge for Ultrapure Microelectronics Fluids and Gases

The Proflow™II-E-SELECT filter cartridge provides exceptional flow rates and on-stream life. It uses a PTFE membrane along with high-purity polypropylene supports that provide an economical alternative to all fuoropolymer cartridges. With its unique SELECT pleating technology, the liquid fow rates are increased by up to 50% verses our standard Proflow®II-E. This filter is ideally suited for ultrapure microelectronics fuids and gases. It is available dry or wet-packed for quick installation and lower extractables.
