Collection: FilmTec™ Membranes

DuPont FilmTec™ Commercial & Industrial Membranes (RO & Nanofiltration)

Engineered for uncompromising water purity, this comprehensive collection features industry-leading DuPont FilmTec™ (formerly DOW) reverse osmosis and nanofiltration membranes. Manufactured in the USA to the highest quality standards, these advanced thin-film composite spiral-wound elements provide exceptional structural integrity and highly consistent performance for commercial, industrial, and marine fluid processing applications. Whether you are outfitting a high-salinity offshore desalination rig or executing a low-energy brackish water purification system, FilmTec™ elements deliver superior salt rejection, steadfast durability, and long-lasting operational efficiency.

This extensive catalog spans a wide range of specialized membrane configurations to meet precise system requirements. It features the rugged SW30 and SW30HRLE series tailored specifically for marine watermakers and coastal desalination, which operate reliably at 800 PSI test conditions across various standard footprints, including 2.5" x 14", 2.5" x 40", and 4" x 40" configurations. For commercial brackish and tap water applications, the collection offers high-efficiency LC, BW30, and XLE models designed to maximize flow rates at lower applied pressures ranging from 100 PSI to 225 PSI, yielding exceptional rejection rates up to 99.6%. Additionally, precision nanofiltration elements like the NF90 and NF270 series are available for specialized organics removal and water softening at ultra-low operating pressures of just 70 PSI.
