FilmTec™ ECO-440i

(Suggested alternative: Hydranautics ESPA2-MAX)


DOW FILMTEC ECO-440i Elements offer unparalleled rejection and flow performance for your industrial water needs, enabling lower energy usage and reduced regeneration costs in downstream polishing units. With a new industry-leading performance of 99.7% rejection at 150 psi, DOW FILMTEC ECO elements provide robust performance over a longer element life. Compared to standard RO elements, DOW FILMTEC ECO-440i elements can deliver up to 40% lower salt passage at 30% less energy—an ecological and economical win. iLEC™ Interlocking End Caps reduce system operating costs and the risk of o-ring leaks that can cause poor water quality.
