The AXEON HF4-4021 Reverse Osmosis Membrane is engineered for high-flow, high-rejection performance in commercial and light industrial reverse osmosis applications. Manufactured using advanced thin-film composite (TFC) membrane technology, this element delivers efficient dissolved solids reduction while maintaining strong permeate flow and reliable system efficiency.
Supplied in a dry-shipped configuration, the HF4-4021 provides extended shelf life and simplified storage prior to installation. Its 4.0″ × 21″ size makes it well suited for compact commercial RO systems, specialty installations, and OEM equipment requiring high-flow performance in a shorter membrane length.
Features:
- High-flow reverse osmosis membrane
- Dry-shipped for extended shelf life
- Advanced thin-film composite (TFC) technology
- High permeate output with consistent rejection
- 4.0″ × 21″ membrane size
- Designed for commercial and light industrial RO systems
