In the former report, advantages of using a small duct for an air conditioning system were mentioned, and it was presented that the mixed flow multiblade fan, which was developed newly by authors, was adequate to a small duct fan. In this paper, the effects of parameters of the mixed flow multiblade fan on the fan performances were investigated experimentally. At first, the effects of a conical angle of the impeller and a vane setting angle on the performances were investigated. Then, two types of guide vanes were examined, and it was made clear that the guide vanes which overhang the impeller gave remarkable effects on the fan pressure and efficiency. At last, the experimental results regarding to effects of the inlet and outlet vane angles were presented.
