Specifically Designed for Liquid Filtration
- Enhanced cleanability and microbiological safety due to crevice-free, polished and hygienic design
- Corrosion resistance and durability with 316L stainless steel wetted parts and high-quality welds
- Cost-effective without sacrificing quality and performance
Features and Benefits
- T-style multi-round housing • Suitable for flow rates up to 227 liters/min (60 USgpm) depending upon cartridge type and size
- Suitable for CIP and SIP
- Beveled housing tubesheet and aseptic-style housing seal provides enhanced drainability and a crevice-free connection between the housing head and bowl
- Electropolished head and elbows and mirror polished bowl ensures optimal cleanability in critical areas while maintaining cost-effectiveness
- New cartridge locking design features additional cut-outs to traditional half-moon portions of the Code 7 bayonet locks, enhancing cleanability and drainability
- Operator-friendly V-Band housing closure simplifies handling
- Housings with clamp coupling and butt weld connection options meet the design requirements of 3-A Sanitary Standards #10-04

1Maximum operating pressure ratings are vessel ratings only. Safe operating temperature and pressure will depend on filter cartridge and seal used. For compatibility details, please contact Pall.
2For applications involving fluids below 0 °C (32 °F), please contact Pall.
3Check local pressure vessel code requirements.
4Seal materials meet FDA requirements for food contact use detailed in 21 CFR Section 177.2600 (excluding milk and edible oils). Additionally, seal materials in 3-A Series housings meet the requirements specified by 3-A Sanitary Standards #10-04.
5Refer to Pall Food and Beverage filter cartridge literature for additional guidelines on use.
6The flow/pressure drop curve refers to the empty housing only, for water at 20 °C (68 °F). For other liquids, multiply housing pressure drop by the specific gravity of the fluid.
This is a guide to the part numbering structure and possible options only. For availability of specific options, please contact Pall.
