Poly Fine II Filter Cartridges

Summary

Product identification

The PALL POLY-FINE® II Series comprises filter cartridges designed for consistent performance, high contaminant holding capacity, and wide chemical compatibility. They feature a rigid polypropylene outer cage and all-polypropylene one-piece construction, except for the 0.2 µm grade. The 0.2 µm grade utilizes asymmetric polysulfone media. These cartridges are suitable as submicron prefilters for final membrane applications.
