  • Axial impeller and fan having such an axial impeller
    Patent number: 10670044
    Abstract: An axial impeller for a fan or blower includes a hub and a plurality of blades. The geometry of the blades is determined by a course of a blade leading angle and of a blade trailing angle of blade sections from a blade root at the hub to a blade tip opposite the blade root, i.e., according to the hub ratio. The blade leading angle is curved to the left according to the hub ratio and/or the blade trailing angle is curved to the right according to the hub ratio and the blade leading angle is 29°±3° near the blade root and 14°±3° near the blade tip and/or the blade trailing angle is 69°±3° near the blade root and 27°±3° near the blade tip.
