This devise is directed to a dust collector. Dust collector is a dust collector which are mounted to the work surface in order to suction the dust generated in the upper side of the work table, the first filter, the first case the first filter is installed therein, a first member formed on top of the first case the suction hole, and the first filter, and the dust is above the first including the circumference of the top of the first filter to the bottom of the batchineun gap adjusting device of the first filter so as to abut along the periphery around the first suction hole 1 includes a motor that causes a suction filter, and wherein the gap adjusting device adjusts a height of the first filter so that the gap (gap) is not generated between the top when the top member and the first case of the first filter . According to the subject innovation, the suction port as much as possible and reducing the gap that occurs between the filter unfiltered dust can be prevented from being leaked to the outside, the fine dust generated during grinding of the workpiece through the small double filter efficiently collecting You can. In addition, the water film is formed due to a number of microporous activated carbon particles inside the charcoal or filtering effect may be further improved, the cleaning of the residual particulates can be made to maximize the usability of the filter, is filtered by the moisture in the air discharged meogeumge The humidifying effect can be achieved. And if you do not hardly affects the workspace can be made even more efficient dust collector, dust collector consists of a bench with a one-piece can be moved easily.본 고안은 집진기에 관한 것이다. 집진기는 작업대의 상측에서 발생되는 분진을 흡입하기 위해 상기 작업대에 설치되는 집진기로서, 제1 필터, 상기 제1 필터가 내부에 설치되는 제1 케이스, 상기 제1 케이스의 상단 부재에 형성되는 제1 흡입 홀, 그리고 상기 제1 필터의 상단의 둘레가 상기 제1 흡입 홀 주변에 둘레를 따라 맞닿도록 상기 제1 필터의 하단을 받치는 갭 조정 장치를 포함하는 제1 필터부, 그리고 상기 분진이 상기 제1 필터로 흡입되도록 하는 모터부를 포함하고, 상기 갭 조정 장치는 상기 제1 필터의 상단과 상기 제1 케이스의 상단 부재 하면 사이에 갭(gap)이 발생되지 않도록 상기 제1 필터
