摘要： To provide a dust collector which, even when it is used in a poor power supply situation, can detect the dust loading of a filter accurately, can remove dust automatically and can reduce power consumption. In the dust collector, there is provided a control circuit which can detect the dust loading of a filter by comparing the threshold value of the dust loading pressure to be determined by the internal pressure of the filter, the operation of a suction device, the power supply frequency of the suction device and the supply voltage of the suction device with the filter internal pressure just before the suction device stops, and, when the filter is dust loaded, can operate a dust removing device.
