The AXEON NF3-4021 Nanofiltration Membrane is designed for selective separation in commercial and light industrial water treatment applications requiring partial salt rejection with lower operating pressure than reverse osmosis. Utilizing advanced thin-film composite (TFC) nanofiltration technology, this membrane effectively reduces hardness, color, and organic compounds while allowing partial passage of monovalent salts to help maintain balanced water chemistry.

Supplied in a dry-shipped configuration, the NF3-4021 offers extended shelf life and simplified storage prior to installation. Its 4.0″ × 21″ size makes it well suited for compact commercial nanofiltration systems, specialty installations, and OEM equipment requiring efficient NF performance in a shorter membrane length.
