PURPOSE: A small-sized dust collector is provided to improve efficiency of dust collection by simultaneously performing an adsorption process and an discharging process of foreign materials and to easily discharge the foreign materials through self-weight. CONSTITUTION: A small-sized dust collector comprises: a housing(100) having one or more intake duct, one or more exhaust duct, and a filter fixing part(140); one or more filter part(200) adsorbing foreign materials flowing in from the intake duct; a main blower part(300) offering a driving force for discharging the air without foreign materials to the outside of the collector; a compressed air spray part(400) dropping the adsorbed foreign materials to the lower part of the collector by spraying compressed air in the filter part; a foreign material storage which stores the dropped foreign materials; a cyclone part(700) separating a transferred foreign material from the air and discharging the foreign material; an air conveyer blower part(600) transferring the stored foreign material to the cyclone part with the air; and a controller(900).
