Abstract
This electrostatic filter dust collector has a dust collecting section which is assembled by using a mini-plate type filter member having a small width of the fold thereof and a short distance between the adjacent ridge portions thereof. Since a plurality of insulating spacers are inserted at suitable intervals into the filter member from the upstream and downstream sides thereof, the percentage of the contacting area of the spacers with respect to the filter member is low, and the percentage of the dust collecting area thereof is high. Electrodes are provided on the upstream and downstream ridge portions of the filter member, and a high voltage is applied between these electrodes, so that a uniform and stable electric field is generated on the filter member as a whole. This enables a high dust collecting efficiency to be obtained.
