TW30-1812-50HR DuPont FilmTec Membranes

DuPont FilmTec™ TW30-1812-50HR Residential RO Membrane (50 GPD)

The DuPont FilmTec™ TW30-1812-50HR is a premium, high-rejection residential reverse osmosis membrane engineered to deliver exceptionally pure drinking water for home point-of-use (POU) systems. Manufactured in the USA utilizing advanced polyamide thin-film composite (TFC) technology, this highly reliable element provides superior removal of dissolved solids, heavy metals, and typical tap water contaminants. Designed specifically as a "High Rejection" (HR) model, it consistently yields outstanding water quality and system efficiency, outperforming standard replacement elements and ensuring safe, pristine water for household consumption.

Built to the industry-standard 1812 configuration (1.8-inch diameter by 12-inch nominal length), this element drops seamlessly into standard residential RO pressure vessels. Evaluated under typical tap water test conditions at an applied pressure of just 50 PSI, it produces a reliable nominal permeate flow rate of 50 gallons per day (GPD) while maintaining an exceptional stabilized salt rejection rate of 99.0%. Shipped dry for extended shelf life and rapid system start-up, this durable, professional-grade membrane provides the steadfast hydraulic performance and long-lasting dependability required by modern under-sink drinking water filtration systems.
