3M Betapure AU Series Filters

3M Betapure AU series filter cartridges and capsules set the standard for filtration performance. Offering more grades with absolute reduction ratings than competitive filters, the controlled pore size of the Betapure AU series filter matrix allow for absolute distinction between cartridge grades to provide the most accurate and consistent filtration.

The 3M Betapure AU series filter provides:

  • Precise Contaminant Reduction
  • Consistent Effluent Quality
  • Superior On-stream Service Life

3M Betapure AU series filters, available in 18 distinct grades with absolute ratings from 2 to 190 microns to tailor the exact selection of performance characteristics for the greatest filtration economy by providing distinct reduction cut-off points by particle size.  Betapure AU series filter manufacturing combines advanced incoming material quality assurance, exacting in-process controls, and extensive final product testing and verification. The result is a filter product that provides consistent filtration lot-to-lot, filter-to-filter.

Features & Benefits of 3M Betapure AU Series Filters

The Rigid Construction Advantage

To meet demanding filtration quality standards in today’s market, absolute ratings will provide product consistency, and improve product yields.

The rigid filter structure retains consistent pore size even under severe process conditions. Changes such as those caused by pump fluctuations, stopping and restarting the system, or high differential pressure will have minimal, if any effect on product consistency. Depth filtration reduces deformable contaminants to help eliminate rework or product quality rejection.

Critical to any filtration process is the reduction of filter by-pass. A closed cell polyethylene foam gasket ensures proper cartridge sealing
when using knife-edge housing systems.

Minimizing flow restriction dramatically reduces filtration cost! Lower pressure drops mean increased filter life, product throughput, and
permit the use of fewer filters to achieve a given flow vs. differential pressure.

Filters appropriately sized for a specific application reduces total filtration costs including purchase, installation, and disposal.
