For "Sterile" Filtration of Beer
Pasteurizer replacement filter cartridges are hydrophilic membrane filters designed for reliable retention of spoilage microorganisms in the filtration of beer in the CFS NEO system or standard housings.
Description
The Pasteurizer Replacement filter cartridge family was developed and validated for removal of beer spoilage microorganisms in the CFS NEO system or standard housings.
The Pasteurizer Replacement filter cartridges are constructed from one layer of polyethersulfone (PES) membrane in a laid-over-pleat configuration. The single open ended (SOE) configuration is designed to fit into the sanitary housings on the CFS NEO system and standard housings to ensure effective microbial reduction and assembly integrity.
Pasteurizer Replacement filter cartridges are suitable for exposure to repeated hot water sanitization and in situ steam sterilization cycles for longer service life in the CFS NEO system. The optimized support and drainage materials, provide increased mechanical strength during operation, repeated hot water, chemical and steam sanitization and thus, high throughput.

Technical Information
Operating Characteristics in Compatible Fluids1
| Maximum Differential Pressure | Operating Temperature |
| 4.0 bard (58.0 psid) (forward pressure) | 80 °C (176 °F) |
| 1.0 bard (14.5 psid) (reverse pressure) | 40 °C (104 °F) |
1 Compatible fluids are defined as those which do not swell, soften or attack any of the filter componants.
Chemical Cleaning (static soak conditions)2
| Media | Temperature | Cumulative Exposure |
| Caustic 2% | 50 °C (122 °F) | 400 hours |
| Caustic 2% | 80 °C (176 °F) | 200 hours |
2 Measured under laboratory test conditions. The actual cumulative time depends on the process conditions.
Pressure Drop3
| Code | Value |
| PAREQII | 42.5 l/min @ 100 mbar (7.6 US gal @1psi) |
3 Typical initial clean media differential pressure (dP) per 254 mm (10”) cartridge for water at 20°C (68°F), viscosity 1 centipoise. For 508, 762 and 1016 mm configurations, divide the differential pressure by 2, 3 and 4 respectively.
Sterilization and Sanitization
| Media | Temperature | Cumulative Exposure |
| Steam | 125 °C (257 °F) | 125 x 20 min cycles |
| Hot water | 90 °C (194 °F) | 200 x 30 min cycles |
| Peracetic acid (PAA), 325 ppm PPA (1275 ppm H2O2 to give 1600 ppm of total peroxides) |
Ambient | 2000 hours |
*Measured 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.
