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.

• 100% efficient removal rating
• Consistent, verifiable filtration

• Extraordinarily high dirt holding capacity
• Long service life
• High flow rates
• Excellent gel removal capability

• No solids unloading under variations in flow or pressure differential
• Fibers will not migrate or become dislodged and contaminate the process fluid

• Extremely good chemical compatibility with a wide range of fluids
• Very low extractables
• No surfactants or binder resins are used during manufacture
• Continuous construction without side seam
• Media melt-sealed to solid components to ensure maximum integrity

• All materials of construction are FDA listed
• All polypropylene components have been tested according to U.S.P. class VI biological tests for plastics at 121°C
• Batch traceable
• Statistical testing of filter effluent for:
• • particle and fiber counts
  • Total Organic Carbon (TOC)
  • pyrogens using LAL test
  • pH shift test

Operating Characteristics

• Maximum Operating Differential Pressures and Temperatures in Compatible* Liquids

• Steam sterilizing temperature (in-situ or autoclave) for Cartridge styles AB Code 3 ‘P’ grade, AB Code 7: 125°C (257°F)

• Maximum recommended cumulative steam life at 125°C (257°F): 10 hours

Note: Differential pressures are for liquids with a viscosity of 1 centipoise (cP). Differential pressures for liquids at other viscosities can be conservatively estimated by multiplying the indicated differential pressure by the viscosity in cP. For cartridges of 508 mm (20"), 762 mm (30") and 1016 mm (40") nominal length, divide the differential pressure by 2, 3 and 4 respectively. To obtain the total pressure drop of a complete filter assembly the housing pressure drop must be added. Please refer to the relevant housing literature or contact Pall.
