GS-12-Air Flow Pattern
The GS-12-Air is designed to circulate water by bringing water from along the tank floor and sending
it upward and out across the water surface in layers causing direct and induced mixing effects. The
air diffuser creates thousands of tiny bubbles which produces a "Low Pressure Zone" that creates an
uplift suction flow through the intake draft tube, and a slight mound at the water surface, producing
gentle flow radially outward from the AP Unit.
The near laminar layers flow outward radially, in diverging stream lines directly above the GS-12-
Air. As flow leaves the Unit, vertical flow is induced in between the water being drawn below and the
water above. At the level of the flow intake, water is drawn from all inner walls and along the floor
of the tank. As this lower layer of fluid makes its way inward with converging streamlines to the GS-
12-Air, the water is forced upward, toward the surface, providing gentle mixing, de-stratification, and
surface renewal.
The GS-12-Air Unit requires a minimal amount of supplied air. The air is supplied to the GS-12-Air
Unit with the provided air feed hose that connects to air manifold.
It is acceptable to use the Unit on an as needed or required basis. This will allow for reduced power
consumption and will benefit in energy savings. This will require the Unit to run on a timer or local
SCADA system.
Refer to air supply manufacturer for recommended duty cycle and other operational
recommendations and constraints.
