Serial layers of depth media and membrane provide long lasting protection of final filters

Extended life and high retention efficiency make Clearflow™ an ideal filter for the clarification of particulate-laden solutions as commonly found in food and beverage production.

At the heart of the Clearflow™ design is a serial layer matrix of depth media and polyethersulfone (PES) membrane. This combination offers superior flow and long-lasting protection for downstream final filters. Clearflow™ cartridges are also non-fiber-releasing and will not unload contaminants, even under pulsing conditions.

Clearflow™ cartridges are available in 0.2, 0.5, or 0.8 µm nominal ratings, and with your choice of glass fiber or polypropylene prefiltration media. They are manufactured in a certified clean room environment. The Biological Grade version provides qualitative microbial retention. General Grade cartridges are for prefiltration applications, and are bulk packaged and economically priced.
