RO-4040-FF DuPont FilmTec 2,400 GPD at 225 PSI 4 x 40 inch Membranes

DuPont FilmTec RO-4040-FF Sanitary Grade RO Membrane (2,400 GPD)

The DuPont FilmTec RO-4040-FF is a high-performance, sanitary-grade reverse osmosis membrane engineered specifically for the food, beverage, pharmaceutical, and medical industries. Designed to fit standard 4-inch by 40-inch pressure vessels, this element utilizes an advanced polyamide thin-film composite membrane. Its specialized "full-fit" configuration eliminates the traditional brine seal and outer wrap, minimizing stagnant areas where bacteria could grow. This ensures a highly sanitary design that fully complies with U.S. Food & Drug Administration (FDA) indirect food contact requirements.

Built to deliver high yields of exceptional quality water, the RO-4040-FF is ideal for demanding applications where the permeate is the final product, such as evaporator condensate polishing and specialized medical water systems. Under standard manufacturer test conditions, this element delivers a reliable nominal permeate flow rate of 2,400 gallons per day (GPD) at an applied pressure of 225 PSI. With a stabilized salt rejection rate of 99.5%, it provides robust and consistent removal of dissolved solids and contaminants, ensuring maximum safety, compliance, and continuous productivity for rigorous commercial sanitary applications.
