4" Sanitary Ultrafiltration Elements
3838 Element
Synder's 4" sanitary ultrafiltration elements are USDA compliant and well suited for small production scale operations, or large volume pilot studies. With pore sizes ranging from 1KD to 500KD, these elements are ideal where flow is limited below the requirement of larger production scale elements.
