The AXEON NF4-4021 Nanofiltration Membrane is engineered for enhanced separation performance in commercial and light industrial water treatment applications. Utilizing advanced thin-film composite (TFC) nanofiltration technology, this membrane provides higher rejection than standard NF membranes while operating at lower pressure than reverse osmosis, making it effective for reducing hardness, color, and organic compounds with improved efficiency.
Supplied in a dry-shipped configuration, the NF4-4021 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 reliable, high-performance NF operation in a shorter membrane length.
