MAX Sanitary Ultrafiltration Spiral-Wound Element:
A6 (PVDF 500kDa)
Synder Filtration’s MAX Series of Ultrafiltration Elements offer exceptional physical and chemical durability, in the same wide range of MWCO’s as our standard UF elements. Contact us today to learn more about our complete line of membrane products and services.
A6 has the largest pore size of all the ultrafiltration membranes, with a molecular weight cut-off of 500kDa. While V6 is used for cathodic electrocoat paint recovery, A6 has the same pore size but is used for anodic electrocoat paint recovery, surfactant cleanup and recovery, and mine wastewater reuse. This membrane is also suitable for applications involving fat and microbial removal. Along with the other membranes, A6 is available in flat sheet, standard spiral-wound elements, and custom configurations upon request.
MAX SERIES BENEFITS
- Conforms to 3-A, FDA, and USDA sanitary standards
- Elimination of chlorine during CIP with hot sanitation
- High resistance to pH, temperature, & fouling
- Customizable dimensions for unique housings
COMMON APPLICATIONS
- Anodic electrocoat paint
- Microbial/Particle removal

TECHNICAL NOTES
For element sizes not listed, please call or email Synder Filtration for details. We can design an element to fit your exact needs – just specify the element outer diameter (OD) or vessel/housing inner diameter (ID), element inner diameter (ID), and length. Elements are also available with or without a controlled bypass tail. Additional feed spacers are also available. Trials should be conducted to determine optimal application conditions.
