Developed from traditional depth filtration technology, SUPRApak modules efficiently combine the filtration mechanisms of surface filtration, depth filtration and adsorption. Highly unique to their design is an entirely new flow configuration, based on the "edgeflow" principle.
Seitz® filter sheet material is wrapped around a central, permeable core. Feed and filtrate channels provide a fluid flow path resulting in maximum utilization of the sheet material, to provide highly efficient contaminant removal and a cost-effective enclosed system alternative to flat sheet filtration. New to the SUPRApak PW Series is an improved layer to layer sealing which offers the following features and benefits:
|Flow configuration based on "edge flow" principle||
Sealing line technology
|Enclosed filtration system||
Drainable, low hold-up volume assembly
High filtration capacity in compact design
Simple, quick installation and servicing
Typical applications are found in many fluids in the food and beverage industry.

Operating Characteristics in Compatible Fluids3
|Module Size||Grade||Max. Operating Temperature|
|SUPRApak M, L||PW 5200–PW 7100||80 °C (167 °F) / 8 hours4|
3 Compatible fluids are those which do not adversely affect the filter materials of construction.
Field experience shows that maximum achievable differential pressures vary with the applications and product selection. They are determined by monitoring filtrate quality, and are influenced by several factors. Please contact Pall for details, and refer to SUPRApak module instructions for use.
Nominal Weight and Typical Ash Content
|Module||Dry Weight||Wet Weight Ash||Content5|
(PW 5200 – PW 7100)
5.1 – 5.6 kg
15.5 –16.5 kg
|40 – 54%|
(PW 5200 – PW 7100)
25 – 30 kg
(55 – 66 lbs)
|40 – 54%|
5 These figures are determined on typical finished articles. Values differ for individual PW grades. Ash values for the filter sheets in individual batches are available on request.
Many applications in the food and beverage industry are ideally suited to the use of SUPRApak technology, resulting in significant commercial and technical advantages.
|Hot Water||85 °C (185 °F)||20 cycles @ 20 min each|
|Steam||125 °C (258 °F)||10 cycles @ 20 min each|
6The actual time required may vary as a function of the process conditions. Laboratory tests were carried out up to 10 cycles. Actual field experience shows more cycles are achievable, coupled with proper filtrate quality monitoring.
|Module Size||Rising Volume/Module||Recommended Flow Rate|
|SUPRApak M||140 liters (37 gal)||1.5 times filtration flow rate|
|SUPRApak L||340 liters (90 gal)||1.5 times filtration flow rate|
