TW30 PRO-4040 DuPont FilmTec 2,600 GPD at 225 PSI 4 x 40 inch 99.7% Rejection Tap Water Membranes

DuPont FilmTec TW30 PRO-4040 Tap Water RO Membrane (2,600 GPD)

The DuPont FilmTec TW30 PRO-4040 is an industry-leading, professional-grade tap water reverse osmosis (RO) membrane engineered for demanding commercial water treatment applications. Fabricated with advanced polyamide thin-film composite technology, this 4-inch by 40-inch element delivers exceptional reliability and high-purity water production. By building upon decades of proven membrane performance, the PRO series offers enhanced structural durability and superior fouling protection, ensuring stable, long-term operation for commercial facility water systems, food and beverage service setups, and medical research institutions.

Designed for maximum efficiency, the TW30 PRO-4040 features a tape-wrapped outer shell, making it a highly economical choice for systems operating with one or two elements per pressure vessel. It incorporates a robust 34-mil feed spacer, which effectively mitigates the impact of particulate fouling and allows for a broad pH range (1-13) during routine short-term chemical cleaning procedures. Under standard manufacturer test conditions at 225 PSI, this heavy-duty element delivers a remarkable nominal permeate flow rate of 2,600 gallons per day (GPD) while maintaining an industry-leading stabilized salt rejection rate of 99.70%. Capable of safely withstanding a maximum continuous operating pressure of 600 PSI, this membrane guarantees consistent, premium-quality water yields for commercial applications requiring the stringent removal of dissolved solids.
