Absolute-rated pleated depth filters combining long service life and high flow rates

Description

To keep pace with advancing technologies, Pall continues its tradition of filtration innovations with the Profile® Star filter: a state-of-the-art concept for pleated polypropylene filters. This major development in filter technology incorporates the proven successes of the Pall Profile II depth filters and HDC® II pleated filters to provide the only absolute rated pleated depth filter. The proven and successful Pall technique of varying the fiber diameter produces a pore size gradient from coarse (upstream) to fine (downstream) while maintaining constant high void volume throughout the depth of the filter medium. Profile Star filters offer longer life than many competitive pleated filters. Due to their proprietary construction, Profile Star filters deliver the benefits of both traditional pleated polypropylene and depth style filters - the ideal combination. The pressure drop and flow capability is comparable to competitive pleated polypropylene filters whilst also providing excellent removal of soft contaminant, such as gels, because of the depth of the medium.

Profile Star filters are available in absolute removal ratings from 1.0 µm to 90 µm and in four nominal cartridge lengths:  254 mm (10"), 508 mm (20"), 762 mm (30") and 1016 mm (40"). Their all-polypropylene construction makes them compatible with an extremely wide range of fluids. Cartridges are also available in a ‘P’ grade which is optimized for pharmaceutical applications.
