MEMBRAcart XP filter cartridges are hydrophilic membrane filters designed for removal of spoilage microorganisms in the food and beverage industry.
MEMBRAcart XP filter cartridges are filters constructed from an inert polyethersulfone membrane which, in combination with the robust construction enables excellent mechanical strength and exposure to repeated hot water, chemical and steam sanitization cycles for long 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.

Operating Characteristics in Compatible Fluids2
The maximum allowable differential pressure in a forward flow direction for MEMBRAcart XP filters is shown in the table below.
|Temperature||Max. Allowable Differential Pressure|
|Up to 40 °C (104 °F)||500 kPa (5 bard) (72.51 psid)|
|40 °C to 80 °C (104 °F to 176 °F)||300 kPa (3 bard) (43.51 psid)|
2 Compatible fluids are defined as those which do not swell, soften or attack any of the filter components.
Sterilization and Sanitization
|Media||Temperature||Maximum Cumulative Time/Cycles3|
|Steam||125 °C (257 °F)||50 hours / 150, 20 minute cycles|
|Hot water||85 °C (185 °F)||50 hours / 100, 30 min cycles|
|Peracetic acid (PAA), 325 ppm PAA (1275 ppm H2O2 to give 1600 ppm of total peroxides)||ambient||2000 hours|
3 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.
Pressure Drop vs Liquid Flow Rate4
4 Typical initial clean media differential pressure (dP) per 254 mm (10 in.) cartridge for water at 20 °C (68 °F); viscosity 1 centipoise. For 508, 762 mm and 1016 mm configurations divide the differential pressure by 2, 3, and 4 respectively.
