The Dow Filmtec XLE-4021 reverse osmosis elements offer better system performance and economics by operating at very low applied pressure. The Filmtec XLE-4021 membrane is made with a patented technology and provides consistent and reliable system performance. The new XLE series of elements replaces the Dow Filmtec TW30LE elements which were made with an older membrane technology. Tape-wrapped elements are built with the same high quality membranes and materials of construction as industrial elements, without the hard outer shell. This makes them more economical for commercial systems with one or two elements per housing. The Filmtec XLE-4021 is the most productive, lowest pressure RO membrane element. The Filmtec XLE-4021 may be cleaned over the widest pH range (pH 1-13) for the most effective cleaning. Dimensions: 3.9-inch W X 21-inch L.
