PROBLEM TO BE SOLVED: To improve reliability by eliminating malfunction of water level sensors.SOLUTION: In a dust collector, a body 5 storing an air intake unit and having filters on the upstream side is placed on a tank having a suction port so as to suck outer air or water from the suction port by the operation of the air intake unit, and also a pair of electrodes 70, 70 for detecting the level of water stored in the tank are arranged by projection on the lower surface of the body 5. A guard plate 67 for performing partitioning between the suction port and filter units is arranged on the lower surface of the body 5. The electrodes 70, 70 are arranged on a surface on the opposite side of the suction port in the guard plate 67. |
