DUST COLLECTING FILTER, NATURAL AIR SUPPLY OPENING USING THE SAME AND DUST COLLECTOR

摘要

PROBLEM TO BE SOLVED: To provide a dust collecting filter without requiring a high voltage power source which prevents short circuit as defects by having two electrodes having a potential difference of a conventional electrical dust collector while preventing contamination from a blowout port by charged dust and generating ozone.

SOLUTION: There is provided the dust collecting filter, in which a corrugated plate-like insulating plate 3 is put on a plate-like electrode plate 2 so that a longitudinal cross section becomes waveform, wound as roll-like and grounded the plate-like electrode plate 2. A natural air supply opening using the dust collecting filter and a dust collector are also provided.
