Profile® Star Filter Cartridges

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. 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 while also providing excellent removal of soft contaminants, 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 in.)
  • 508 mm (20 in.)
  • 762 mm (30 in.)
  • 1016 mm (40 in.)

Their all-polypropylene construction makes them compatible with an extremely wide range of fluids. Cartridges are available in a P grade which is optimized for pharmaceutical applications.

Note: These filters are also available in Kleenpak Nova capsule format.
