GEHNY

Summary

Product identification

GEHNY-Series High Purity Electronics Grade Nylon and Plus+ Nylon Filter Cartridges feature a nylon 6,6 membrane, providing superior particulate retention and cleanliness for ultra-pure water production in the micro-electronics industry. The optional positive zeta potential surface charge (Plus+) enhances retention performance for particulates smaller than the stated micron rating.

Cartridges are manufactured in a clean room environment and undergo extended flushing with 18 megaohm ultra-high purity water to achieve extraordinarily low levels of extractable substances and provide quick rinse-up. Each element is diffusion tested for integrity.
