OenoClear™ W Grade Filter Cartridges

Pall Corporation has designed the OenoClear cartridges for the wine industry as a complete, reliable and economical alternative to sheet (pad) filtration. A fully enclosed hygienic cartridge filtration assembly can be utilized in applications such as final clarification, pre-filtration and yeast removal in wine processing. Having been specifically engineered for the wine industry, OenoClear cartridges incorporate a unique, polyaramid membrane in a single open ended (SOE) AB style cartridge to fit in a sanitary housing to ensure complete yeast removal and allow repeated regeneration in situ. This combination of efficient yeast removal and extended service life enable OenoClear filters to replace sheet filtration, offering improved performance and better economics.
