DUST COLLECTOR

PURPOSE:To obtain a dust collector capable of collecting various kinds of dusts and having an excellent general-purpose property, by mounting dust collection mechanisms each having a filter mounted thereto to the front and rear parts of the dust collector main body in a freely openable and closable manner. CONSTITUTION:A dust collector main body 1 has various dust collection means such as a filter 4, a dust box 13 or the like and a fan 2 mounted therein. A pre-dust collection part 8 having a bag-shaped filter 7 mounted thereto in a freely detachable manner is mounted to the front part of the main body 1 and a post-dust collection part 15 having a fine dust collecting filter 11 mounted thereto is mounted to the rear part of the main body 1 in a freely openable and closable manner. By selecting the bag-shaped filter 7 corresponding to the kind of dust, the dust collecting function of the filter 4 can always be kept constant. Further, fine dust unable to be collected in the front stage can be collected by the fine dust collecting filter 11.
