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 fluoropolymer cartridges. With its unique SELECT pleating technology, the liquid flow rates are increased by up to 50% verses our standard Proflow II-E. This filter is ideally suited for filtering high-purity chemicals and solvents often used in critical microelectronics processes. It is available dry or wet-packed for quick installation and lower extractables.
