The Chemflow-PE SELECT filter cartridge uses a PTFE membrane along with HDPE supports that provide an economical high performance alternative to all-fluoropolymer cartridges. It provides a high degree of cleanliness and retention as low as 30 nanometers. With its unique SELECT pleating technology, the liquid flow rates are increased by up to 50% compared to our standard Chemflow-PE. This filter is ideally suited for ultrahigh purity chemical and solvent manufacturing, bulk chemical delivery and lower temperature wet processes (<60°C). It is available dry or wet-packed for quick installation.
