Aerator
OPERATION
The wind powered aerator was designed to be a stand alone product for pond
and lake aeration. Anchored in a lake, it draws water through a 12" tube
from the lake bottom and discharges it just below the surface. This continuing
process results in raising water low in dissolved oxygen to the surface to be
naturally oxygenated by wind and wave action. It also keeps an area open during winter months.
(Detailed description of
stratification and aeration by the Illinois
EPA. These pages are an excellent explanation of these two areas.)
SETUP
The aerator has three floats that position the discharge tube
just below the water surface. These are aluminum cases filled with flotation
foam.
The actual windmill is a Savonious two stage rotor optimized
for maximum efficiency. It is directly coupled to a 12" stainless steel
impeller turning in a 24" long tube. This tube connects to a 12"
flexible rubber hose which can be any length. A anchor connector at the bottom
of this hose allows the aerator to be positioned at a specific location. The
anchor itself can be as simple as a couple of concrete blocks.
The rotor starts to turn in the slightest breeze and will
turn about 100 RPM in a 10-15 MPH wind.
INTRODUCTORY PRICING $1695
We prefer pickup at the factory due to our extreme hatred of
crate building and high motor freight shipping costs.
Crating is an additional $150.00 and shipping costs depend on
the customers location. The aerator rotor is completely assembled but requires
assembling the three floats, impeller and housing.
