Advances in Filter Media

Pore Size Characterization with PMI Online Bubble Tester and PMI Cartridge Porometer

Filtration process involves inserting a barrier or static structure into a dynamic air or fluid stream to allow separation of certain components from that stream. The actual separation is performed by the membrane or filtration media used within these filters. Understanding the size distribution of the pores that completely pass through the separating layer will define the sizes of particles, which can be transported through the filter, and those that are removed from the fluid stream.

The Online PMI Bubble Point Tester provides an ideal QC/QA platform for fast and accurate bubble point (largest pore) measurement of filter media and cartridges, whereas Automated PMI Filter Cartridge Porometer provides fully automated through-pore analysis of entire filter cartridges of various geometries. Tests include bubble point, pore size distribution, mean pore size, gas, liquid, and Frazier permeability, and filter integrity. Sample chamber design permits use of cartridges having diameter and length over a wide range from several feet to several inches. Pore size characterization with PMI Online Bubble Point Tester and Automated PMI Cartridge Porometer provides great deal of pore size information to QC/QA and R&D Managers with flexibility to use various liquids like water, mineral oil, alcohol or commercially available Galwick, Silwick, Porewick solutions under various conditions of flow rate and pressure.
