DOW FILMTEC™ XLE-4021 Low Energy Reverse Osmosis Membrane Element



DOW FILMTEC XLE-4021 Elements offer better system performance and economics for small commercial systems by operating at very low applied pressure. DOW FILMTEC XLE-4021 elements are tape-wrapped. In addition to high quality water and low energy costs, DOW FILMTEC membranes also deliver savings by providing long lasting and reliable performance.



DOW FILMTEC Brackish Water Reverse Osmosis Elements can separate salts from water and are produced with an automated fabrication process for precision, consistency, and reliability. DOW FILMTEC RO membranes build on a tradition of leadership in the thin-film composite membrane industry and meet the challenges of higher rejection in lower-pressure operations.



DOW FILMTEC XLE-4021 is FDA – 21 CFR 177.2550; Food and Drug Administration Compliant.

Work perfectly for feeding our cat
Wanted the convenience and hygiene of single use cat dishes. They do not absorb liquid from wet food and last for several hours if necessary without soggy problems.
