The 3M Beta Pure AU40B11NN Ordering Guide Betapure filter manufacturing utilizes state-of-the-art technology to produce a clean, rigid, filter structure with consistent and reproducable filtration characteristics. The filter matrix is constructed using long bicomponents fibers, each fiber having an inner core and an outer sheath. The bicomponent fibers of the filter matrix are thermally bonded by utilizing the difference in melt temperatures of the two fiber components. Heating the matrix to the melt temperature of the polyethylene sheath, but below that of the polypropylene core, causes the fiber-to-fiber bond at every contact point. The high degree of fiber-to-fiber bonding provides a rigid structure that eliminates the need for a core support and any possibility of media migration.

The Betapure filter ensures that the unwanted particles are removed because:

• The rigid structure maintains its porosity throughout the filter life.
• The depth structure removes more difficult deformable contaminants.
