4″ Nanofiltration Elements

4" Sanitary Nanofiltration Elements

3838 Sanitary Element

4" NF elements are ideal for low volume production operations or large scale pilot studies. Synder's sanitary elements are fully USDA compliant and offer excellent rejection of divalent and multivalent ions.  Consistently displaying an unmatched combination of flux and rejection against the industry standard, the NFX and NFW membranes are ideal where 150-500D membrane pore sizes are required.

4" Industrial Nanofiltration Elements

4040HM Element

Synder Filtration's 4" industrial nanofiltration elements are ideal where both 150-500D membrane pore sizes and zero bypass are a necessity.  Manufactured with a durable fiberglass casing or more economical tape wrapping, Synder's elements offer an integrated ATD with multiple permeate tube options.  This flexibility matched with unmatched flux and rejection, make the NFX and NFW the ideal choice for the rejection of divalent and multivalent ions.
