GFPES

Summary

Product identification

GFPES-Series High Purity Food and Beverage Grade Polyethersulfone Filter Cartridges are designed for demanding food and beverage industry requirements. They offer high flux density and low protein-binding, maintaining organoleptic characteristics. Cartridges are flushed with ultra-High Purity water to reduce extractable substances. Each element is diffusion tested for integrity. Manufactured in a clean-room environment.
