3M BNA020 Specifications

CUNO’s BevASSURE BNA020 series filter features a new asymmetrical polyether sulfone (PES) membrane with Advanced Pleat Technology (APT) construction. This design results in a robust filter that is optimized for both long service life and fast flowing applications, while providing 0.2 µm rated filtration for superior removal of microorganisms.
high standards for microorganism control. Combined with CUNO’s range of particle control and prefiltration filter cartridges, BevASSURE BNA020 series final filters offer bottlers a complete solution for rigorous contaminant control while maintaining long service life and low operating costs.
Durable Design
The BevASSURE BNA020 series filter membrane and cartridge design innovations result in a highly durable filter cartridge, capable of secure operation through numerous cycles of hot water sanitation and chemical based cleaning and sanitation protocols.
ADVANCED TECHNOLOGIES Highly Asymmetric BNA020 Membrane
BevASSURE BNA020 series filters incorporate a novel single layer PES membrane with a high degree of asymmetry (Figure 1). When viewed in cross-section, the membrane contains larger pores on the upstream surface that gradually taper to smaller pores towards the downstream surface. Compared to conventional membranes with a symmetric pore structure, this structure provides greater contaminant capacity, since it presents greater open spaces (void volume) in which to retain these contaminants. This increase in capacity leads directly to longer service life. In addition, the asymmetric structure provides less resistance to flow, resulting in a lower pressure drop when compared at a constant flow rate to competitive filters, allowing a user to employ fewer BevASSURE BNA020 series filters for any given flow rate.

Advanced Pleat Technology Design
BevASSURE BNA020 series filters feature Advanced Pleat Technology (APT) design for extended service life. This design technology maximizes the useful surface area of the filter while maintaining open flow paths between the media pleats (refer to Figure 2). By employing the APT design, the BevASSURE BNA020 series filter provides lower pressure drops, longer service life, and lower overall operational costs.

ADVANCED PERFORMANCE
Extended Service Life
In the majority of beverage applications, the final membrane filter is used in a continuous (as opposed to a batch) operation. Its service life is measured either by the volume filtered, or the number of days in service, before becoming permanently blocked. Filters that provide longer service life not only reduce direct operational costs, but also reduce indirect filter costs as well (filter change-out/installation labor, downtime between change-outs, filter flushing, etc.). The BevASSURE BNA020 series filter’s combination of highly asymmetric PES membrane, Advanced Pleat Technology design, and novel upstream/downstream supports all work together to maximize the volume of beverage that can be processed.
Advanced Microbiological Control
The primary purpose of a membrane filter cartridge in bottled water and beverage processing is to effectively control even the smallest microorganisms. BevASSURE BNA020 series 0.2 micron rated filters provide superior retention of common spoilage microorganisms, even at challenge concentrations that far exceed those experienced by most beverage producers.

Novel Media Support Design
BevASSURE BNA020 series filters employ a design that results in higher beverage flow versus pressure drop compared to competitive filters. This CUNO development combines the high flowing PES membrane with special support layers upstream and downstream of the membrane. When combined with the previously mentioned Advanced Pleat Technology, this feature greatly increases flow per cartridge, and results in lower overall operational costs

Fast Flow Rates at Low Pressure Drops
CUNO has combined three key technological advances to provide the fastest flow rate per unit of pressure drop. These three technologies, Advanced Pleat Technology (APT) design, a novel upstream and downstream support design, and a highly asymmetric microporous membrane, afford users with faster process flow rates using fewer filters as compared to alternative filters.
