SW30-2540 FilmTec 2.5 x 40″ Seawater Membrane

FilmTec SW30-2540 Seawater RO Membrane – High Efficiency Desalination Solution

The FilmTec SW30-2540 Seawater Reverse Osmosis (RO) Membrane is a high-performance solution designed for reliable desalination in marine, offshore, and yacht watermakers. With a compact 2.5″ diameter x 40″ length, this industry-standard size ensures seamless compatibility with leading brands such as Spectra, Stella, Selmar, FCI, and Schenker.

Built with DuPont FilmTec’s trusted polyamide thin-film composite technology, this seawater RO membrane delivers exceptional salt rejection of 99.4% and a high permeate flow rate of 2.6m³/day, making it an ideal replacement element for small desalination systems.

Its durable fiberglass shell ensures long service life in demanding marine environments, while its design supports operation at lower pressures to minimize pump size, cost, and energy consumption.

Whether you’re operating onboard a yacht, offshore, or in a small seawater desalination plant, the SW30-2540 guarantees consistent freshwater production, energy efficiency, and reliability.
