AXEON® HF4–Series Reverse Osmosis Membrane Elements operate at extra-low pressures of only 100 psi, while producing a nominal salt rejection rate of 99% and reaching flow rates up to 2,500 gallons per day. 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.
Features:
- Extra Low Energy
- High Flow Capacities
- Improved System Performance
- Superior Quality and Cost Savings
- Individually Vacuum Tested
- Made in the U.S.A.
