The Performance of in-line duct fan depends on the design parameters of impeller and guide vane. such as sweep back angle of impeller, the number of blades, outlet blade angle, guide vane angle etc. In this experimental study total four kinds of impellers having different sweep back angles, 90°, 72.5°, 55°, 37.5° with 8 guide vanes, different the number of blades, 6ea, 8ea, 10ea, 12ea, different kinds of outlet blade angles, 30˚, 45˚, 60˚ and different kinds of guide vane angles, 15°, 30°, 45° were selected and their performance measured to investigate the effects of them. The results were non-dimensionalized to compare their performance.
