ABSTRACT:
An aerator for oxygenating the water in a pond or the like is disclosed, the aerator having a housing with a floatation collar therearound and a motor disposed in a vertically adjustable bracket mounted in the housing. A propeller is secured to the motor shaft and the bracket is adjusted so as to dispose most of the propeller above the surface of the water to create a flow of water from lower levels of the pond through the housing, during operation of the aerator. The propeller is designed to increase agitation, having straightened blade ends and notches cut in the blades, the agitation and spray serving to oxygenate the water and to allow harmful gases to escape to the atmosphere.
