GFHNY

Summary

Product identification

The GFHNY-Series High Purity Food and Beverage Grade Nylon and Plus+ Nylon Filter Cartridges feature a nylon 6,6 membrane, designed for superior microbial retention in highly stable consumables. The optional positive zeta potential surface charge (Plus+) enhances retention for particulates smaller than the stated micron rating, assisting in the removal of haze, color bodies, and endotoxins.

Cartridges are manufactured in a clean room environment and flushed with 18 megaohm ultra-high purity water to achieve cleanliness and low extractables. They are designed to tolerate repeated hot water sanitization and in situ steam sterilization cycles for maximum service life. Each element is diffusion tested for integrity to assure optimal performance.
