Description
The PMI Automated Filter Cartridge Tester 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.
Principles of Operation
A fully wetted filter cartridge is placed in the sample chamber and the chamber is sealed. Gas is then allowed to flow into the cartridge. When the pressure reaches a point that can overcome the capillary action of the fluid within the pore (largest pore), the bubble point has been found. After determination of the bubble point, the pressure is increased and the flow is measured until all pores are empty, and the filter cartridge is considered dry.
Applications
PMI's Automated Filter Cartridge Tester is perfect for quality control and R&D environments. It is fast, accurate, and non-destructive. The Automated Filter Cartridge Tester has applications in any industry that utilizes filter cartridges.
