For High Volume Depth FiltrationSUPRApak Multi-Stack Series-WA housings are designed for use with SUPRApak L filter modules. They revolutionize high volume depth filtration applications in the food and beverage industry, providing a cost-effective alternative to classical sheet filtration.
|Closed filtration system||Increased process safety and product quality; minimized product losses, product contamination risk and personnel exposure to process fluids|
|Compact design with high filtration area||Extremely high throughput at low investment cost|
|Drainable, low holdup volume assembly||Higher product yield; minimized cleaning costs|
|High quality internal surface finish, sanitary and crevice-free design||Enhanced cleanability|
|Flexible modular design||Production volumes can be matched to equipment capacity by using different housing domes|
|External tensioning devices||Provides secure operation without bypass|
|Dual inlet connections||Minimizes product mixing zones|
|Simple, quick installation and servicing||Reduced labor, maintenance and downtime costs|
|Filter module lifting device available on request||Eases filter installation and removal|
SUPRApak Multi-Stack technology is ideal for use in high volume beer, sweetener, enzyme, gelatin, yeast extract, and other food and beverage applications.
SUPRApak Multi-Stack Series-WA units hold from 16 to 24 SUPRApak L modules, representing up to approximately 240 m2 (2583 ft2) of filtration area in a very compact and low hold-up volume design. They are available in single dome design.

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 1, Category IV, Module G). Pressure rating is suitable for hazardous liquids or gases.
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 Multi-Stack Series-WA housings are supplied without accessories.

9 For hot fluid filtration (>40 °C/ >104 °F) select Hot Fluid Core for the top module in the stack and add Hot Fluid Core Extension Z1 (1-high section) and/or Hot Fluid Core Extension Z2 (2-high section) as required.
Lifting device enables insertion and removal of the entire stack of modules. Spacer pictured at the bottom enables lowering module stack onto a suitable raised surface.
Hooks on the lifting device grab the bottom of the SUPRApak module stack for easy handling.
Different bowl heights offer flexibility.
