Engineered for Microbial Stabilization
Ultipor N66 filters incorporate pleated nylon 6,6 media into single open ended (SOE) cartridges to fit in sanitary filter housings. These elements provide reliable, economical and efficient microbial stabilization of beer. Ultipor N66 filters are suitable for exposure to repeated hot water and in situ steam sanitization cycles for longer service life.| Features | Benefits |
| Hydrophilic media in multiple microbial retention ratings |
|
| Cartridges resistant to numerous sanitization cycles produced with no adhesives or surfactants |
|
| Individually serialized cartridges |
Full traceability |
| Qualified for removal of beer specific microorganisms |

Microbial Removal Rating in Liquid
The NF grade (2 media layers) provides a sterile effluent when challenged with Brevundimonas diminuta (ATCC19146) at a level of >107 CFU per cm2 of effective filtration area. Microbial reduction data for specific applications may be available for other media grades, please contact your Pall representative for application specific information.
NF and NL grades are recommended for filtration of water and aqueous fluids. NB, NK and NN grades are recommended for filtration of bulk alcoholic beverages like wine and beer. All grades may be suitable for liquid ingredient filtration. Please contact Pall for assembly sizing based on your specific application.
Typical Flow Rates4
1Compatible fluids are define as those which do not swell, soften or attack any of the filter components.
2Measured under laboratory test conditions. The actual cumulative time depends on the process conditions. For applications requiring Sterilization or Sanitization Pall recommends the use of Code 7 adaptors to ensure filter sealing after cooling. Cartridges should be cooled to system operating temperature prior to use. Contact Pall for recommended procedures.
3Where indicated one hour sanitization cycles were utilized.
4Typical initial clean media differential pressure (ΔP) per 250 mm (10") cartridge for water at 20 °C (68 °F); viscosity 1 centipoise. For 508 mm, 762 mm and 1016 mm configurations divide the differential pressure by 2, 3, and 4 respectively.
