The present invention provides a dust collector which can increase efficiency of collecting dust in the air by uniformly supplying air, inserted through an air insertion pipe, to each cyclone pipe even when a plurality of the unit cyclone pipes are arranged. The dust collector comprises a dust collection tank and a cyclone unit which is installed in the dust collection tank and filters out dust included in external air. The cyclone unit includes at least one unit cyclone which is formed to have an open upper side and an open lower side and has a space formed therein. Gaps for passing external air are formed between the unit cyclones. A center path unit for passing the external air, having passed through the gaps, to the upside of the unit cyclones is formed in the center of the unit cyclones. An air inlet for inserting the external air, having passed through the center path unit, into an inner space of each unit cyclone is additionally formed on one side of an upper end portion of each unit cyclone. |
