SUPRAdisc™ Depth Filter Modules

The Complete Filter System

The SUPRAdisc module design concept combines the advantages of conventional depth filter sheets with the positive features of enclosed filters.

SUPRAdisc Module Concept

Seitz® depth filter sheets have been used for years in a vast array of applications using a range of equipment. With their exceptional mechanical strength they can be  incorporated into SUPRAdisc modules and installed into enclosed filter housings. This arrangement reduces cleaning and cleaning validation, as well as simplifies installation making it easier to handle and dispose of the filters after use.   Each module consists of three major components:
  • Individual filter cells or lenses
  • A tubular center core
  • End adapters

These components can then be broken down further to better understand the robust construction of Pall® SUPRAdisc modules. Individual filter cells are made from the  joining of two Seitz depth filter sheets and using an injection molding process to seal the edges of the filter sheets to create a filter cell. A drainage plate is placed between each filter sheet prior to this process to reduce flow resistance and to improve flow distribution over the entire surface area of the filter sheets. Up to 21 filter cells can be stacked on a tubular core, compressed and joined to form a unit. This design results in a reliable sealing between the filter cells, and provides the structural robustness necessary to prevent product failure or process bypass situations during operation.

SUPRAdisc Module – Filter Media

Almost all grades of Seitz depth filter sheets that are available in flat sheet format are also available in SUPRAdisc modules. Due to their excellent mechanical strength, these sheets can readily be incorporated into modules.

The Complete Filter System

The SUPRAdisc module adapter has two o-rings and a bayonet lock, a concept successfully implemented by the biopharmaceutical industry for filter cartridges.

Consequently, the SUPRAdisc modules can be installed quickly and easily into filter housings accepting this style adapter. SUPRAdisc modules are also available with a flat gasket style adapter.

High Quality and FDA Conformity

The filter media meet the specifications set forth in the US Code of Federal Regulations Title 21, parts 177.2260 e, f, g, h, i, j, k, l, the materials for all polypropylene plastic components are listed in the US Code of Federal Regulations Title 21, part 177.1520.

With regard to food law conformity, the manufacture of depth filter sheets is also subject to ongoing analysis by the German ISEGA Forschungs– und Untersuchungsanstalt mbH, Aschaffenburg.

Technical Service

For best possible results and maximum reliability, Pall recommends performing filter evaluations utilizing your process and process conditions. Pall specialists can provide valuable assistance, either at your facility or in our SLS (Scientific and Laboratory Services) laboratories. Pall offers hands-on assistance and places its extensive technical resources at your disposal in the form of worldwide technical advice, including cost-reduction programs, process review and problem solving.
