Abstract

Improvements to aerators for stirring and aerating liquids, characterized in that the aerator comprises a support element in the form of a flat plate that is adapted, when the aerator is in service, to lie in a horizontal plane and rotate around its vertical axis central, a plurality of paddles angularly spaced and fixed to the underside of said plate and each extending radially from a central area thereof towards its periphery each paddle having a maximum depth below a horizontal reference plane in a position between its ends, and being provided with a plate fixed to its lower edge and which extends on both sides of the pallet along at least a portion of that part of the length of the pallet between its outer end and the position of maximum depth.
