Extra Low Energy DOW Filmtec XLE-4040 RO Membrane 2600 GPD, a 4.0" x 40" Extra Low Energy Reverse Osmosis Membrane that can provide RO quality water up to 2,600 gallons per day at a 15% recovery rate. It can operate at feed pressures ranging from 100 psi to 600 psi with 99% salt rejection. This element offers the highest quality water for small commercial systems purifying less than one gallon per minute(0.2 m³/d) of RO water. 

XLE-4040 elements offer better system performance and economics by operating at very low applied pressure. XLE membrane, made with a patented technology, provides consistent and reliable system performance. And for added convenience, XLE elements are available in a dry state for rapid start-up. These Thin Film-Composite Commercial RO membranes are tape-wrapped making them suitable and recommended for systems with one or two elements per housing. Filmtec membranes also deliver savings by providing the industry’s longest lasting and most reliable performance due to increased resistance to fouling. The new XLE series of elements replaces TW30LE elements which were made with an older membrane technology

This membrane is part of the "Extra Low Energy (XLE) Elements for Commercial Systems" line of products by Dow and are applied in commercial water treatment systems, food service, hospitality industry, medical and research institutions. Its advanced technological design is manufactured for excellent structural stability and more productivity than other elements.
