PROBLEM TO BE SOLVED: To obtain a mist collector without clogging, thereby maintaining maintenance-free or a condition close thereto to regularly exhibit high collection efficiency. SOLUTION: An inflow side collector 2 mounted on a collector case 7 positioned on the upstream side of a centrifugal impeller 1 opens the upper and the lower ends to have a perpendicular, a large number of and an independent air pass, and is constituted of a path aggregate 26 running sucked air from the upper end opening to the lower end opening. If a dimension of a cross-sectional diameter of each air pass in the path aggregate is made 2.0 to 4.0 mm, an increase in pressure loss is avoided, an increase in fan power is suppressed and an operation cost is reduced. The concentration of a collected oil mist is assisted to prompt a flow fall and the running of the sucked air is smoothly carried out. COPYRIGHT: (C)2006,JPO&NCIPI
