抄録

Separator-type HEPA filters are composed of the elements which have square cross section bounded by the two separator walls and partitioned by the filter medium. Therefore, it is possible to characterize the pressure drop of a separator type air filter unit by studying the pressure drop of this filter element. In the present work, air flow distribution and the pressure drop of the filter element were studied through numerical calculations and experiments with the three-dimensional model filter. It was found that an optimum separator height is about 3.0 mm being independent of filter inlet air velocity. At a small separator height, the pressure drop significantly decreases with increasing separator pleating angle, while at a large separator height the pleating angle little affects the pressure drop. The separator-pleating angle and the media resistance coefficient affect the distribution of airflow velocity through the filter media only in the direction of the main air flow.
