Ultipor® N66 Filter Cartridges

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 for a broad range of food and beverage applications.

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	Consistent filtrate quality Targeted microbial stabilization of beverages and ingredients Easy to wet and integrity test
Cartridges resistant to numerous sanitization cycles produced with no adhesives or surfactants	Process reliability  Cost effective filtration
Individually serialized cartridges	Full traceability

Grades	Applications
NF, NL and NA	Filtration of aqueous fluids (e.g. bottled water or ingredient solutions)
NB and NK	Filtration of bulk alcoholic fluids (e.g. wine and beer) or aqueous fluids (e.g. ingredient solutions)

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 cm²of 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.

NA, NF and NL grades are recommended for filtration of water and aqueous fluids. NB and NK 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.
