Couldn't load pickup availability
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.
Features:
- Nanofiltration membrane for selective ion removal
- Dry-shipped for extended shelf life
- Advanced thin-film composite (TFC) NF technology
- Reduces hardness, color, and organic compounds
- Allows partial passage of monovalent salts
- 4.0″ × 21″ membrane size
- Designed for commercial and light industrial applications
