For Clear, Fresh and Cold Stabilized BeerThe 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 Supor® 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.
- Filter materials preserve the organoleptic properties of the product
- Fixed pores, non-shedding membrane, adhesive and surfactant free
- Reliable removal of specific beer spoilage microorganisms as a function of the retention rate
- Broad chemical compatibility
- Repeated sterilization capability for economical operation
- Easy to wet with cold water for integrity test purposes
Food Contact Compliance
- Food contact compliant filters are available. Please consult the Declarations of Compliance for applicable part numbers at the links below.
- BB Final Beer Filter Cartridges Declaration of Compliance
- The materials of construction meet 21 CFR 170-199
- The filters meet the requirements for food contact use, European Regulation (EC) Number 1935/2004 for slightly alcoholic beverages such as beer
Typical Titer Reduction1
|Microbial Removal Rating||Test Organism||Titer Reduction|
|0.45 μm||Lactobacillus brevis||>107|
|0.45 μm||Pediococcus damnosus||>107|
TraceabilityIn order to ensure traceability each filter cartridge is marked on the cage with the part number and batch number. In addition, every filter cartridge bears an individual number. Product name, microbial removal rating, part number and batch number are indicated on the packing label.
Technical InformationAll construction parts of the BB Final Beer filter are thermo-plastically welded, that means no adhesives are used.

1 The typical titer reduction is determined in laboratory liquid challenge tests on 254 mm (10 in.) new filter.
2 The seal materials employed meet FDA requirements for food contact use as detailed in 21 CFR Section 177.2600
3 In fully compatible fluids which do not chemically attack, soften or adversely affect the filter in any way.
4 Measured under laboratory test conditions. The actual cumulative time depends on the process conditions.
QualityStringent quality controls during the manufacturing process and test procedures assure the high quality standard of all Pall filters and fulfill the special requirements of the brewing industry. Manufacture is carried out according to procedures within a Quality Management System certified to ISO 9001. Each individual filter is integrity tested during manufacture.
