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.
Operating Guidelines
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.

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.

8Depending on the application, rinsing with cold or warm water in a forward flow direction is recommended prior to filtration.
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.
