FILMTEC™ NF245-3840/30-FF

Summary

Product Identification

DuPont nanofiltration (NF) membrane elements are designed for dairy processing applications, offering desalting, purification, and other separations for food and dairy processors. All NF245 elements incorporate an improved nanofiltration membrane sheet engineered to reject organics with a molecular weight above 300 amu while allowing monovalent salts to pass.

The FilmTec™NF245-3840/30-FF product features a Mesh Wrap Full Fit outer shell construction.
