  • Filtration material complies with the Code of Federal Regulations, Title 21, Section 177.1520 Item 2.1, for food contact
  • Functional materials (antimicrobials, etc.) can be added to further enhance performance

Material Technology - What is Porous Plastic?

Throughout each POREX Radial Cartridge Filter runs an intricate network of open-celled, omni-directional pores which gives the media consistency throughout the cartridge for a unique combination of filtering capability and structural strength.

Filtration Efficiency

POREX Radial Cartridges are classification type filters that effectively remove particles at and above their respective ratings while allowing most smaller particles to pass through. POREX Radial Cartridges maintain their high particle removal efficiency for consistent, reproducible results throughout the life of the filter.

Filter performance is often expressed in therms of percent efficiency, defined as the ration of upstream particle concentration compared to the downstream concentration that has passed through a filter body (multiplied by 100).


Chemical Resistance

Made from commercially available thermoplastics, POREX Porous Plastics are resistant to a broad spectrum of corrosive chemicals and reagents. The customer should perform appropriate tests to determine the performance of PO(REX Porous Plastics under each specific operating condition.


Flow vs Pressure Drop*

The specific pressure drop values (psi/gpm) per 10" cartridge are provided for each filter grade. POREX Radial Cartridges exhibit superior flow characteristics to other cartridges with comparable micron ratings. The benefits of lower pressure drop are longer cartridge life. higher throughput and lower overall cost.
