For High Throughput Depth Filtration in Enclosed Systems
SUPRApak Plus PR depth filter module design is using the new layer to layer seal technology.
Beyond cellulose, kieselguhr and perlite, filter sheet material of the SUPRApak PR-series contain up to 40% of polyolefin fibers, specially selected for best possible filtration results. These filter sheets are characterised by an increased chemical and mechanical stability. They are therefore particularly suitable for the filtration of aggressive media. An outstanding property of the HR-sheets is their high resistance to cellulose-degrading enzymes.

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 PR Series is an improved layer to layer sealing which offers the following features and benefits:

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.
