SUPRApak L filtration units provide a closed system approach to high capacity depth filtration, maximizing product protection and minimizing product losses. Lower cost of ownership is achieved due to higher throughput, yield improvement, and reduced handling, cleaning, maintenance and downtime costs, when compared to sheet filtration.
SUPRApak L technology is ideal for use in distilled spirits, beer, sweetener, enzyme, gelatin, yeast extract, and other food and beverage applications.
SUPRApak L Series-WA units hold from one to six SUPRApak L modules, representing up to approximately 60 m2 (646 ft2) of filtration area in a very compact and low hold-up volume design. They are available either in single dome or flexible modular design.
SUPRApak L Series-WA housings are designed for use with SUPRApak L filter modules. They revolutionize depth filtration applications in the food and beverage industry, providing a cost-effective alternative to classical sheet filtration.

1 | Maximum design pressure and temperature ratings are vessel ratings only. Safe operation will also depend on filter module and housing gasket use. EPDM assembly seals restrict continuous operating temperature to 130 ºC (266 ºF). For details on module temperature limitations, please refer to SUPRApak module literature. |
2 | Design satisfies EC Pressure Equipment Directive (PED) 97/23/EC (Fluid Group 2, Category II, Module H). Pressure rating is suitable for non-hazardous liquids or gases. The PED category and fluid group classification indicates suitability of housing use on distilled spirits less than 70% by weight absolute alcohol. For such applications, the maximum allowable temperature must be below the flash point. For 70% by weight absolute alcohol the flashpoint is 21 ºC (69.8 ºF). |
3 | Seal materials meet requirements for food contact use as detailed in FDA 21 CFR Section 177.2600, and EC Regulation 1935/2004, including BfR XV and XXI. Please contact Pall for additional options. |
4 | Refer to Pall Food and Beverage SUPRApak module literature for additional guidelines on use. |
SUPRApak L Series-WA housings are supplied without standard accessories. A few optional accessories are available.
