ABSTRACT:
An aspirator aerator for inducing the flow of atmospheric air at high velocity below the surface of a substance so as to allow oxygen to freely and quickly transfer into the substance. The aerator includes an outer tubular housing having an inner tube disposed therein, one end of the housing being associated with an aspiration mechanism for inducing fluid flow through the aerator, the other end of the housing being associated with a drive for driving the aspiration mechanism. The aerator further including a deicing mechanism disposed between the inner tube and the outer tubular housing for deicing the aerator.
The aerator may further be provided with a control circuit for controlling the operation of the drive and deicing mechanism in response to a signal denoting the presence or absence of icing conditions.
