By using the phenomena that the concentration of particles decreased by passing through branch pipes, a rotating filter was developed to remove particles in two phase fluid. Its filtering effect about 2.1mm particles was explained well by the theory of branch pipes. In this report, filtering effects about 8.5 μm particles were studied. It was found that the filtering effects were better than the theoretical values, because the concentration of particle in the boundary layer on the rotating disk was less than that outside of boundary layer. Next, number of suction holes was increased from 8 to 12, and their filtering effects were studied. It was found that the filtering effects decreased with more than 9 holes.
