Oenoclear™ II Filter Cartridges

A Regenerable Solution for Wine Pre-Filtration

The Oenoclear II filter cartridge is the latest development for yeast and colloid removal from wine.

The new Oenoclear II filter media is constructed from a unique liquid crystal polymer specifically noted for its thermal stability, high mechanical strength and good chemical compatibility. When configured into single open ended (SOE) AB style cartridges, the resulting filter allows for repeated regeneration and sanitization in situ for long service life.

The dense polymer matrix provides excellent yeast and colloid reduction making it ideal for wine tanker filling, final polish filtration in the cellar and protection of downstream membrane filters. When combined, the long service life and high removal efficiency enable low operating costs especially when compared to traditional “sterilizing grade” sheet filters.

Typical Flow Rates4

Oenoclear II Filter Cartridges Typical Flow Rates 

1The Oenoclear II Filter Cartridge liquid retention rating is based on modified OSU-F2 test.
2Compatible fluids are defined as those which do not swell, soften or attack any of the filter components.
3Measured under laboratory test conditions. The actual cumulative time depends on the process conditions. Pall recommends the use of Code 7 adaptors to ensure filter sealing after cooling. Cartridges should be cooled to system operating temperature prior to use. Contact Pall for recommended procedures.
4Typical initial clean media ΔP 254 mm (10") cartridge for water at 20 °C (68 °F); viscosity 1 centipoise. For 508 mm, 762 mm and 1016 mm configurations divide the differential pressure by 2, 3, and 4 respectively.
