PROBLEM TO BE SOLVED: To provide a dust collector with an automatic dust removal function for a filter for separating dust from the air, which informs a user of the state of full tank by a warning means when a tank storing dust is full of dust. SOLUTION: This dust collector 1 includes: the tank 2 storing dust; an intake device 7; a filter device 10 for separating dust from the air; a gauge pressure sensor for detecting the negative pressure in the interior of the filter device 10; and a dust remover 14 for removing dust adhering to the filter 13, wherein when the state of negative pressure in the filter device 13 is larger than the threshold of a preset clogging negative pressure, the filter clogging state is decided, and the dust is automatically removed. When a difference in negative pressure in the interior of the filter device 10 during the operation of the intake device 7 before and after the dust remover 14 is operated is smaller than a preset value, it is determined that the tank 2 is full of dust. The user is informed of the state of the full tank 2 by the warning means. COPYRIGHT: (C)2008,JPO&INPIT
