Duke 169742 Reverse Osmosis Membrane Flashgard Service

Product Description

The DUKE 169742 is a replacement reverse osmosis membrane designed for use in Flashgard service RO water filtration systems. This membrane is the core filtration element in a reverse osmosis assembly, responsible for rejecting dissolved solids, contaminants, and minerals from the water supply before it reaches downstream foodservice or beverage equipment. It is installed by qualified service technicians as part of routine maintenance or system rehabilitation on commercial water treatment setups. Replacing this membrane on schedule maintains system performance and protects connected equipment from scale and mineral buildup.

This membrane is intended for commercial foodservice environments where a Flashgard reverse osmosis system is in service. Typical installations include restaurants, cafeterias, coffee programs, and institutional kitchens where water quality directly affects equipment longevity and product consistency. It is a direct service replacement part supplied under the DUKE parts and accessories line for Flashgard RO filter systems.
