3M™ Betapure™ AU Series Filter Capsule

Our wide range of filter porosities allows you to precisely tailor performance characteristics and achieve optimal filtration economy by enabling defined reduction cut-off points by particle size. We developed Betapure™ AU series filter capsules using state-of-the-art technology to produce a clean, rigid, filter structure that generates reproducible effluent consistency. The filter matrix is constructed using long bicomponent fibres, each fibre having an inner core and an outer sheath. Betapure AU series filters are available in two bicomponent fibre structures, polypropylene/polyethylene or polyester/co-polyester, to provide the greatest range of compatibility for your particular process.

In manufacturing the Betapure™ AU Series Filter Capsule we combine stringent material quality assurance standards, exacting in-process controls, along with extensive final product testing and verification. The results are products that provide consistent filtration from lot-to-lot, filter-to-filter. The bicomponent fibres of the filter matrix are thermally bonded with a high degree of fibre-to-fibre bonding. This provides a rigid structure that eliminates the need for a core support, along with any possibility of media migration.
