FIELD: ventilation and air conditioning.
SUBSTANCE: fan impeller has vanes (11) arranged with circumferential distribution and connected to each other by at least one ring in circumferential direction. Fan impeller consists of at least three solid segments (I–VII). They in each case have at least one section (1) of at least one ring, as well as either one blade (11), or at least part of blades. Segments (I–VII) are connected together to form a fan impeller. Sections of ring (1) adjoin to each other located across direction of impeller fan wheel circumference and forming connection sections (15, 16) by edges (4, 5). At least one edge (4) of ring segment (1) of each segment (I–VII) is provided with at least one geometric closure protrusion (18), and at least one edge (4, 5) of ring segment (1) of each segment (I–VII)—at least one recess (17) at least approximately complementary to element of geometrical closure (18).
EFFECT: fan impeller is proposed.
