Description
Oenopure filter cartridges are developed specifically for cold microbial stabilization of wine. The Oenopure cartridge is Pall Corporation's most advanced solution for membrane filtration of wine. The cartridge is constructed from a highly inert media ensuring that the level of organoleptic and colloidal interference is negligible. The polyethersulfone membrane is configured in a “laid over” pleat configuration for increased mechanical strength, filter area and exposure to repeated hot water and steam sanitization cycles for longer service life. The cartridges are available in single open ended (SOE) configurations to fit in sanitary housings to ensure effective microbial removal and assembly integrity.

Maximum Allowable Differential Pressure
The maximum allowable differential pressure in the forward flow direction for Oenopure filters is shown in the table below.| Temperature | Max. Differential Pressure3 | |
| Up to 40 °C (104 °F) | 5.5 bard (80 psid) | |
| Up to 80 °C (176 °F) | 4 bard (60 psid) | |
3 In fully compatible fluids which do not chemically attack, soften or adversely affect the filter in any way
Sterilization and Sanitization
Oenopure filters can be repeatedly steam sterilized or autoclaved in situ, or they can be sanitized with hot water or chemicals.| Media | Temperature | Cumulative Time4 |
| Steam5 | 125 °C (257 °F) | 30 hours |
| Hot water | 90 °C (194 °F) | 80 hours |
| Peracetic acid (PAA) based sanitizer (320 ppm total peroxides) | 20 °C (65 °F | 1000 hours |
4 Measured under laboratory test conditions. The actual cumulative time depends on the process conditions.
5 The maximum allowable pressure drop (forward) during steam steaming at 125 °C (257 °F) is 0.3 bard (4 psid).
Pressure Drop vs. Liquid Flow Rate6
6 Typical initial clean media differential (DP) per 254 mm (10") element for water at 20 °C(68°F); viscosity 1 centipoise. For 505 mm, 762 mm and 1016 mm configurations divide the differential pressure by 2, 3 and 4 respectively.
