ABSTRACT:
An agitator, in particular for dispersing gases in liquids, includes a plurality of blades, with each blade being constructed to have a blade portion bent forwards in a rotation direction. The blade has a trailing end region, which defines a blade portion bent forwards in a rotation direction, and a leading end region, which is bent inwards at an angle in a direction toward the blade portion.
