Sanitary Microfiltration Spiral-Wound Element
FR MAX (PVDF 800,000Da)
Synder Filtration’s Microfiltration Elements offer an optimal combination of both flux and rejection in a comprehensive range of MWCO’s. Contact us today to learn more about our complete line of membrane products and services.
FR is Synder’s most popular microfiltration membrane, used particularly throughout the dairy industry for fat removal, microbial removal, and protein fractionation. With a molecular weight cut-off of 800kDa, it is currently the tightest available membrane within the microfiltration line and is a customer favorite for its optimal combination of flux and separation performance. While it is frequently used for sanitary applications such as whey/casein fractionation, fat/microbial removal, beverage sterilization, wine clarification, oat sweetener clarification, and gelatin clarification, it can also be used for industrial applications such as fermentation broth clarification and the removal of large particulates and bacteria from during wastewater treatment.
MAX SERIES BENEFITS
- Conforms to 3-A, FDA, and USDA sanitary standards
- Hot sanitization eliminates chlorine during CIP
- High resistance to pH and temperature
- High resistance to fouling
- Customizable dimensions for unique housings
COMMON APPLICATIONS
- Fat/Microbial removal
- Protein fractionation

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 available with or without a controlled bypass tail. Trials should be conducted to determine optimal application conditions.
