3M-CUNO Filter Cartridges and Lenticular Modules


Pre & Final Filter Cartridges
3M-CUNO's leadership in fluid purification has expanded by continually providing superior products and services. 3M-CUNO filtration systems are designed and manufactured to the most stringent industry standards.

LifeASSURE BLA Pre-filter
Benefits
  • superior protection of final membrane filters
  • prefilters, featuring the innovative FlexN™ membrane design, protect and extend final membrane service life, greatly reducing overall filtration costs
  • increase final filter life substantially, often by 10 times or more
  • decrease filter change-outs, greatly reducing filter costs
  • significantly reduces effluent microorganism content
  • unmatched flexibility in creating a multi-zone membrane that offers the maximum in contaminant holding capacity while maintaining high retention efficiency
  • eliminates dual-layer membrane construction to provide a larger surface area, significantly increased contaminant holding capacity, and longer service life
  • 0.65 micron nominal cartridges, in stock
 

LifeASSURE BA II Nylon Final Membrane Cartridges
Benefits
  • durable, high surface area, cleanable membrane filters provide the final barrier to spoilage organisms
  • microbiologically stable fine wines and low per-case filtration costs
  • enhanced hot water stability
  • allows casting of an integral membrane onto a variety of substrates
  • microporous membrane with characteristics providing increased flow and reduced pressure drop
  • superior bacteria retention
  • maximized surface area
Design
  • cartridge designed to provide enhanced mechanical and thermal resistance
  • longer service life even under the most demanding process conditions
  • 0.65 µm rated filter removes contaminating yeast, molds, and most spoilage bacteria from wine
  • 0.45 µm rated filter removes not only yeast and molds, but even the smallest spoilage bacteria such as Oenococcus oeni, at significant levels
 

LifeASSURE BNA PES Final Membrane Cartridges

 
  Cartridge Filters for Beverage Microbiological Stability
Controlling the spoilage microorganism population prior to packing is critical for many beverage processors. Eliminating these microorganism, while keeping other beverage properties unchanged is
of vital importance. Of equal importance, however, is attaining long on-stream filter service life and driving down operating costs associated with filtration. 3M-CUNO has solved this demanding problem with the creation of the LifeASSURE BNA PES series of filter cartridges. LifeASSURE BNA PES filters encompass new, leading-edge technologies that not only provide the highest degree of microorganism control, but do so in an extremely durable and long-lasting design.

LifeASSURE BNA PES filters employ a new, highly-asymmetric polyether sulphone (PES) membrane


 that delivers excellent spoilage microorganism retention while greatly minimizing any organoleptic interference. This highly durable membrane/cartridge design withstands repeated exposure to hot water sanitation and steam sterilization as well as common chemical cleaning and sanitizing agents.

Complementing this high-performance membrane are 3M-CUNO’s patented Advanced Pleat Technology (APT) design and a patent pending upstream and downstream support design. All three work in concert to provide and increased flow rate at a lower pressure drop, resulting in smaller filter assemblies with extended service life and lower overall operation costs.
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 by 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 labour, downtime between change-outs, filter flushing, etc.).


The LifeASSURE BNA PES filter’s unique combination of highly asymmetric PES membrane, Advanced Pleat Technology design, and a novel upstream/downstream supports all work together to maximize the volume of beverage that can be processed. The LifeASSURE BNA PES filter’s unique design provide more than twice the throughput of the nearest competitor, greatly reducing overall filtration costs.
