The present invention relates to a dust collector comprising a housing including an inhaling hole for polluted air, a discharging hole for purified air, and a body part for connecting the holes; a filter installed in the housing; and a pulse bar for regenerating the filter by providing compressed air in the shape of a pulse in the opposite direction of flow when filtered by the filter. The filter has an upper cap mounted on an upper part thereof and a venturi tube mounted on the upper cap to transmit compressed air effectively to the surface of the filter. The pulse bar includes a cylinder part in a lengthwise direction separated upward from the opening part of the venturi tube and having one side surface opened and the other side surface closed; and a pipelike guide extending downward from the cylinder part and having a top and a bottom thereof opened. The guide has a first spray hole and a second spray hole being opening parts in a lengthwise direction for discharging compressed air to the side of the filter formed on the lower surface thereof, and includes a forming part for spray holes in a lengthwise direction between the first spray hole and the second spray hole so that the first spray hole and the second spray hole can be separated. |
