ELECTROSTATIC FILTER-VENTILATOR Russian patent published in 1994 - IPC

FIELD: filters-ventilators. SUBSTANCE: animating negative and positive electrodes are enclosed in housing and are electrically connected with high-voltage current source. Electrodes are enclosed in electric housing. Negative electrodes are made in form of pointed conducting fins evenly located on inner surface for mounting at different angles to transverse and longitudinal axes of housing. Positive electrodes are made in form of row of conducting screens located at outlet of air from filter-ventilator in parallel to each other. First screen holds conducting point equidistant from negative electrodes. EFFECT: enhanced efficiency. 2 dwg
