| 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 |
Specifications
SUPRApak Multi-Stack 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 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.
SUPRApak Multi-Stack Series-WA housings are supplied without accessories.
5 Pall Corporation reserves the right to make dimensional modifications at any time, maintaining the same fit, form, and function. Please request a general arrangement drawing if exact dimensions are required.
