An axial flow cyclone dust collector with fixed guide vanes ( called simply as a cyclone) is applied in many industrial fields. Therefore, it is used widely in all over the world. Until now, the various constructions of cyclone is devised. However, the report which described collection performance or flow characteristic depended on shape of exit pipe is very few. In order to explain the separation characteristic depended on the diameters D_2 and D_f, this paper describes the detailed radial distributions of the tangential and axial velocities in the separation chamber. The velocity distributions were meassured with a cylindical Pitot tube with single hole. Here, main sizes of the cyclone are the body diameter D_1 of the cyclone, exit pipe of diameter D_2, the imaginaly cylindical length Hi, a max funnel diameter D_f and as well as the angle of the fixed guide vanes θ _B as D_1=99 (mm), D_2=33 (mm), Hi=134 (mm) and θ _B=45° Funnel ratio D_f/D_1 was changed as 0.5,0.6 and 0.7.
