Abstract

A surface aeration impeller incorporating a stabilizer cylinder that damps out and eliminates any sustained oscillatory or vibratory displacements normal to the axis of rotation when the impeller is in operation. The surface aeration design operates in a mechanically stable fashion under diverse loading conditions and at any static liquid level submergence of the impeller.
