Beschreibung
Zusammenfassung:Fan wheel (1) comprising a first (2) and second (3) end plate, and blades (5) arranged between the first (2) and the second (3) end plate and joined to the first and the second end plate. In order to obtain an efficient fan wheel the outer surfaces (31) of the blades (5) are inclined in relation to the rotation axis (9) of the fan wheel (1), the first (2) and second (3) end plate have outer portions which protrude radially outward beyond the outer edges (8) of the blades, the outer portion of the first end plate (2) is generally curved or inclined towards the second end plate (3) and the outer portion (12) of the second end plate (3) is generally curved or inclined away from the first end plate (2), and the blades (5) are profiled to have a profile where the thickness of the blades vary between the outer edges (8) of the blades (5) and the inner edges (14) of the blades.
