描述
PREcart PP II filter cartridges are extremely robust and high performance pleated depth filters designed for particle removal in food and beverage applications.
The PREcart PP II filter element is designed to meet the high mechanical resistance and compatibility requirements of typical food and beverage production cycles of filtration, sanitization, regeneration and steam sterilization.
It is frequently used in a wide variety of applications requiring excellent particle removal. Satisfying filtrate quality specifications or effectively prolonging the life of downstream final filters, Precart PP II is a proven and versatile solution for the food and beverage industry.

Technical Information
The technical information provided is based on controlled laboratory tests done on typical production filters at the conditions described, unless otherwise indicated. Actual operating conditions may affect the filter's performance.
Performance
Operating Characteristics in Compatible Fluids1
| Maximum Differential Pressure | Operating Temperature |
| 5.0 bard (72.5 psid) (forward) | 25 °C (77 °F) |
| 2.0 bard (29 psid) (forward) | 80 °C (176 °F) |
| 1.5 bard (21.8 psid) (forward) | 90 °C (194 °F) |
| 1 bard (14.5 psid) (reverse) | 60 °C (140 °F) |

Typical Flow Rates2
2 | Typical initial clean delta p per 254 mm (10 inch) cartridge, water at 20 °C (68 °F). For liquids with viscosity greater than 1 cP, multiply the delta p by the viscosity |
Sterilization and Sanitization3
| Method | Maximum Temperature | Maximum Number of Cycles4 |
| Steam Sterilization (forward) | 134 °C (273 °F) | 25 x 30 minutes |
| Hot Water Sanitization (forward) | 90 °C (194 °F) | 50 x 30 minutes4 |
3 | For applications requiring in situ 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. |
4 | Extensive field experience indicates these filters show excellent resistance to hot water sanitization, typically 50 30-minute cycles at temperatures of 80-90 ºC (176-194 ºF). |
Backflushing
Extensive field experience indicates that these filters withstand over 50 20-minute hot water backflushing cycles at up to 60 °C (140 °F) and maximum 1 bar (14.5 psid). The cleaning effectiveness is a function of several parameters. The use of DOE filters is not recommended.
