摘要： A fountain aerator for propelling and aerating water includes a float having a flow tube extending therethrough for suspending the aerator in a body of water. A motor base assembly contains a motor provided with a rotatable output shaft. An open ended housing is spaced from the float and connected between the flow tube and the motor base assembly. A wear ring is secured within the housing and defines a central opening therein. A covered impeller is retained in the housing in spaced relationship with the float and is coupled to the motor output shaft for rotation therewith. The impeller has a series of radially extending blades which define a series of outlet passages in communication with the inlet. A flow straightener is spaced from the float and fixed to the housing in overlying, surrounding relationship with the impeller. The flow straightener has flow straightening slot structure overlapping the outlet passages of the impeller for propelling substantially vertical streams of water upwardly through the flow tube.
