PROBLEM TO BE SOLVED: To remove mist adhering to an inside peripheral surface of the casing of an axial flow fan used in a machine shop or the like where mist such as lamp black occurs. SOLUTION: A collector 3 bent toward inner side in an outlet part of a casing 2 is installed, an introducing port 31 for mist opening to the inner side of the casing and collecting space 32 for mist are formed. The introducing port 31 for mist and the collecting space 32 for mist are communicated and separated with a partition part 33. Mist 8 moving downstream on the inner peripheral surface of the casing 2 with a rotary blade 1 is taken from the introducing port 31, collected in the collecting space 32 and is discharged from a drain port 34.
