SUPRApak™ SW Series Module–L (16”)
For High Throughput Depth Filtration in Closed Systems
SUPRApak SW series depth filter modules set a new standard for enclosed sheet filtration, providing exceptional throughput and removal performance.
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 “edge flow” 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 closed system alternative to flat sheet filtration.

Operating Characteristics in Compatible Fluids3
|Module Size||Grade||Max. Operating Temperature|
|SUPRApak L||SW 5200-SW 7300||75 °C (167 °F) / 8 hours4|
|SUPRApak L||SW 7700||ambient|
3Compatible fluids are those which do not adversely affect the filter materials of construction.
4Laboratory tests up to 8 hours exposure. Actual field experience shows substantially longer resistance to high temperatures. For continuous hot fluid applications over 40° C (104° F), a stainless steel support core is required. Please see SUPRApak housing data sheet for information.
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|
(SW 5200-SW 7300)
|Hot Water||85 °C (185 °F)||1.5 bard (21.7 psid)||20 cycles @ 20 min each|
7The 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 L||340 liters (90 US gal)||1.5 times filtration flow rate|
SW 7700 Modules
Due to the high permeability of SUPRApak SW 7700 modules, initial clean water differential pressures at the typical flux rates used for these modules are negligibly low and influenced by measurement accuracy.
