<p>A surface aerating rotor has an intake zone for circulating and aerating a liquid, and includes a supporting assembly, a driving shaft connected to the supporting assembly, fixed flow guidance devices disposed in the intake zone of the rotor, and a plurality of fluid throughput units. Each fluid throughput unit has a discharge opening, and includes a vane which has an adjustable discharge angle with respect to the radial direction, and at least one flow guide wall. At least some of the fluid throughput units include an extension member downstream of the discharge opening, a flow guide profile on the extension member, and a baffle downstream of the flow guide profile. Connecting pins join the fluid throughput units to the supporting assembly, for adjustment of the vane discharge angle within a predetermined range.</p> |
