AXEON NF3-4014 Nanofiltration Membrane Element, Dry
AXEON NF3 - Series Nanofiltration Membrane Elements are designed for applications requiring lower rejection rates and higher flux than a standard RO membrane element. Nanofiltration is widely used to reduce scale-forming, hydrated divalent ions while allowing smaller hydrated monovalent ions to pass through. NF3 - Series Membrane Elements offer high flow rates up to 2,200 gallons per day at an operating pressure of 70 psi, and feature rejection rates of 40 - 50%. Lower operating pressures provide improved RO system performance and energy savings.
Benefits:
- All Industry Standard Sizes
- Nanofiltration Membrane Elements
- Improved RO System Performance
- Superior Quality and Cost Savings
- Individually Inspected, Qualified and Vacuum Tested
- Private Labeling and Customization Available
