FILMTEC™ LC LE PRO-4040 Low Pressure (Low Energy) Commercial RO Membrane ElementDirect Replacement for DOW FilmTec LC LE-4040 FilmTec LC LE PRO-4040 Elements deliver high quality water at low pressure at harsh water conditions, using technology for low energy commercial applications. DuPont’s fully automated element production enables consistent products and minimizes the total cost of ownership of water treatment systems. DuPont Filmtec (Formerly DOW FILMTEC) Brackish Water Reverse Osmosis Elements separate salts from water and are produced with an automated fabrication process for precision, consistency, and reliability. 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. FILMTEC LC LE PRO-4040 is FDA – 21 CFR 177.2550; Food and Drug Administration Compliant.   FILMTEC LC LE PRO-4040 is the direct replacement for DOW FilmTec LC LE-4040, which has been discontinued by the manufacturer. | | Specifications for LC PRO LE-4040 | | | | FilmTec Product: | LC LE PRO-4040 | | FilmTec Part Number: | 12081512 | Replaces Models:
