Abstract

An impeller (2) for a radial fan (1) adapted to rotate about a rotation axis (A) comprises a plurality of main blades (25) that are sequentially arranged about such rotation axis (A), and having radially innermost inlet ends (32) and radially outermost outlet ends (33). Each of the main blades (25) comprises a concave main blade first surface (26) and a convex main blade second surface (27) opposite the main blade first surface (26) and facing the main blade first surface of the successive main blade. The main blade first surfaces (26) define main blade arcs (PP) which comprise a first (PP1), a second (PP2), a third (PP3), and a fourth (PP4) main blade circle arcs that are radially arranged from the inside to the outside of the impeller (2), and having a first (R1), a second (R2), a third (R3), and a fourth (R4) main blade radii of curvature, respectively. The main blade radii of curvature (R1, R2, R3, R4) have ratios in the following ranges: R2/R1=1-1.1; R3/R1=1.1-1.2; R4/R1=1.2-1.5.
