ABSTRACT:
A partially housed air-water rotor is mounted for rotation about a horizontal axis. A water pipe on the axis serves as one bearing for the rotor, while an air pipe on the axis serves as another bearing for the rotor. The rotor ends have nozzles effective to mix the air and water and to direct discharge thereof in opposite tangential directions in a plane normal to the axis and from said housing through a vertical slit in the side of a spa tank.
