💧 DuPont FilmTec LC LE PRO-4040 Low Energy RO Membrane
🌟 Product Description & Key Benefits
The DuPont FilmTec LC LE PRO-4040 is a premier, high-surface-area Low Energy (LE) Brackish Water (BWRO) membrane element. It is engineered to deliver high-quality permeate water at a significantly reduced operating pressure, making it the ideal choice for new and existing commercial systems focused on maximizing energy efficiency and lowering operational costs.
-
Low Energy (LE) Performance: Tested and rated at only 150 PSI (10.3 bar), it provides exceptional flow and rejection while using less power than standard BWRO elements (225 PSI).
-
High Flow Output: With a nominal flow rate of 2,750 GPD, this 4-inch element offers a high-productivity solution for light commercial and industrial applications.
-
Superior Rejection: Utilizes FilmTec's advanced technology to achieve a stabilized 99.5% salt rejection, ensuring high-quality purified water output.
-
Standard Size: Fits all standard 4-inch diameter membrane housings.
