An aerator for aerating a pool of water employs a rotor defining a number of flow channels extending from an axial inlet to a peripheral outlet. When the rotor is supported partiaily immersed in the pool of water with the axial inlet immersed in the water and is rotated about the axis, centrifugal effects propel water from the axial inlet to be expelled from the peripheral outlet, |
