Abstract
Symmetric tubular ceramics exhibiting a 50% porous volume and mean pore diameters centered around 11, 13 and 15.5 μm, respectively, were tested in aerosol filtration using sodium chloride particles in the range of 0.01–0.7 μm in diameter and face velocity varying from 0.6 to 4 cm/s. The evolution of particle penetration and pressure drop was measured in function of pore size, membrane thickness and air flow velocity. The filtration results given as a function of the filter characteristics and of the operating conditions show that these filters can be classified as high efficiency particulate air filters whether as HEPA or ULPA standards.
