Abstract
Specifications of the impeller and the scroll type casing of a multiblade radial fan comprising an impeller having numerous radially directed blades circumferentially spaced from each other and a scroll type casing accommodating the impeller are determined so as to make divergence angle of the scroll type casing substantially coincide with divergence angle of the free vortex formed by the air discharged from the impeller.
