BB Final Beer Filter Cartridges

For Clear, Fresh and Cold Stabilized Beer

The new Pall BB Final Beer filter cartridges have been especially designed and qualified for the brewing industry for secure and reliable removal of harmful beer spoilage microorganisms. The SuporĀ® medium is a highly efficient polyethersulfone membrane which, in combination with the construction of the BB Final Beer filter, ensures excellent service life and filtration results.

This new filter cartridge, due to the high mechanical strength and improved titer reduction increases the potential for filtration to replace pasteurization for final beer treatment.

The AB style cartridges are available in single open ended (SOE) configurations to fit in sanitary housings to ensure effective microbial removal and assembly integrity.

The BB Final Beer filter is THE choice for microbiological stabilization prior to beer being sent to filling machines.

This filter is integrity testable. An in-situ and non-destructive integrity test can provide assurance of filter performance within minutes. Integrity tests help manufacturers avoid costly issues such as product contamination, product losses, reprocessing and production delays, as well as satisfying auditor requirements.
