AXEON HF4-4040 Reverse Osmosis Membrane, 40 Inch x 3.9 Inch

The AXEON HF4-4040 Reverse Osmosis Membrane is engineered for reliable, high-rejection performance in commercial and light industrial RO applications. Built with advanced thin-film composite (TFC) membrane technology, this element delivers consistent dissolved solids reduction while maintaining stable permeate flow and system efficiency.

Supplied in a dry-shipped configuration, the HF4-4040 offers extended shelf life and simplified storage prior to installation. Protected with a hard ABS shell for improved structural integrity, HF4–Series RO Membranes are the upgraded choice for extra-low energy savings and for reducing costs and applying less stress on RO system fittings and components.
