The Omnipure CSM5672S is a 50 GPD thin-film composite RO membrane engineered for direct compatibility with 3M SQC reverse osmosis systems, replacing discontinued Water Factory and CUNO models 66-4706G2 and 66-4703G2. This membrane delivers reliable permeate production in Ionics and older 3M commercial filtration platforms without integrated check valve or flow restrictor components.

COMPATIBILITY & APPLICATIONS
Designed For 3M SQC Systems
The CSM5672S membrane is a drop-in replacement for 3M Water Factory and CUNO SQC-style reverse osmosis systems, as well as older Ionics commercial RO units. This membrane requires a host system with integrated check valve and flow restrictor components, as these are not included with the membrane element itself. Ideal for facilities maintaining legacy 3M filtration infrastructure or requiring OEM-compatible replacement membranes for established water treatment installations.
💧 This membrane ships without check valve or flow restrictor because 3M SQC systems integrate these components into the housing assembly. Verify your system configuration before ordering to ensure compatibility with standalone membrane elements.
