8" Sanitary Nanofiltration Elements
8040 Element with ATDs
Synder Fitlration's 8" sanitary nanofiltration elements are revolutionizing liquid filtration where 150 to 500D membrane pore sizes are required. Fully USDA compliant, these elements offer unmatched rejection and flux against the industry standard in large, productions scale operations. Ideal for the rejection of divalent and multivalent ions, Synder's NF operates significant lower pressures than RO elements and can be an excellent alternative where high salt rejection isn't a necessity.

8" Industrial Nanofiltration Elements
8040HF Element
Synder Fitlration's 8" industrial nanofiltration elements are revolutionizing liquid filtration where 150 to 500D membrane pore sizes are required. Manufactured with a robust fiber glass casing or a more economical tape wrapping, these elements offer unmatched rejection of divalent and multivalent ions as well as typically displaying 30-50% greater flux than the leading competitor. We urge you to put these elements to the test against the industry standard.
