DOW FilmTec Membrane Elements

DUPONT FILMTEC™  TW30 PRO-2540 Commercial Reverse Osmosis Membrane Element

 Direct Replacement for FilmTec TW30-2540, which is now obsolete. 

DUPONT FILMTEC (Formerly DOW FilmTec) TW30 PRO-2540 Elements are the industry standard for reliable operation and production of the highest quality water in commercial applications. DuPont DOW FILMTEC TW30 PRO-2540 elements are tape-wrapped—built with the same high quality membranes and materials of construction as industrial elements, except for the hard outer shell, and are more economical for commercial systems with one or two elements per housing.

DuPont 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.

DuPont FILMTEC TW30 PRO-2540 is the direct replacement for TW30-2540 which has been discontinued by the manufacturer.
