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 terms of percent efficiency, defined as the ratio of upstream particle concentration compared to the downstream concentration that has passed through a filter body (multiplied by 100).

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.
* Based on cumulative data supplied by an independent laboratory. Flow rates are based on the media and may be limited by the core of the cartridge or the cartridge housing.
