💧 DuPont FilmTec™ XLE-4040 Element
Product Description
The DuPont FilmTec™ XLE-4040 is a premier 4-inch Extra Low Energy (XLE) Reverse Osmosis (RO) membrane element, designed for outstanding performance in commercial brackish water applications. This element utilizes advanced thin-film composite (TFC) technology to deliver a high flow rate of 2,600 GPD at an impressively low operating pressure of just 100 PSI. The XLE-4040 achieves a reliable stabilized salt rejection, providing excellent water quality while drastically reducing the energy consumption and capital costs associated with high-pressure pumps. Its efficiency and durability make it the element of choice for water stores, car washes, small municipal facilities, and commercial water purification systems seeking optimal operational savings.
