A stirring element (10), especially a gasing stirring element for stirring liquids and introducing a gas, preferably air, to the liquids. The stirring element has a hub (12) for attachment to a stirring shaft and a support disk (14) joined to the hub (12), a plurality of stirring blades (16) being attached to a peripheral edge of the support disk (14). To achieve a low output power coefficient, each stirring blade (16) is made of a wedge-shape that is directed in the direction of rotary motion of the stirring element (10). Preferably, radially inner end sections (22, 24) of two sides (18, 20) of the stirring blade (16) are angled relative to sides (18, 20) outwardly with reference to the direction of rotary motion of the stirring element (10). The stirring element (10) simplifies gas feed and prevents clogs. By providing the support disk (14) with a conical shape having a ring of teeth (26) on its outer edge, a uniform distribution and good dispersion of the gas bubbles is obtainable.
