Windmills provide beauty, efficiency and better health for your pond!
The
Best Way to Aerate
There are two main ways to aerate your pond,
lake or reservoir
By Surface or Diffused Aeration
Surface Aeratio n
- are systems that come in the form of Fountains or Jets
and are
primarily used to produce surface level oxygen. They splash the water back to
the surface, similar to that of a rain, and only help to control top level algae
and weeds. They do that by pushing the weeds and algae out of the center and
back to the shoreline. They do not aerate down to the bottom. This type of
aeration looks attractive but as research indicates, is one of the most
ineffective ways to keep the water healthy. Oxygen never gets to the bottom of
the water, where it is needed to help break down the organic sludge that
constantly enters the water and sinks to the bottom.
Diffused Aeration
– are systems where air is pumped into the water, t hrough
airline attached to air diffusers that lie
at the bottom of the pond, lake, or reservoirs. This achieves total pond
aeration from the bottom to the top regardless of the depth of the water. These
systems are both more effective and economical, for it requires far less energy
to push air in a diffused aeration system than it does pushing water through
fountains or jets. Diffused aeration also helps to oxygenate and de-stratify
the pond. Windmills are ideally suited for areas needing aeration without
electricity nearby and can be located hundreds of feet away from the water's
edge, as necessary to catch more wind.
Windmill Aeration systems will:
·
Help prevent algae and weed
growth
·
Help prevent water discoloration
·
Eliminate thermal stratification
·
Reduce the Biological Oxygen
demand
·
Reduce the sedimentation rate
causing a build up of sludge and muck
·
Improve water clarity and
cleanliness
·
Reduce chemical use and costs of
chemicals
·
Reduce overall costs of
maintaining a healthy pond, lake, pond or reservoir
·
Eliminates fish kills and
promotes healthy aquatic life
·
Eliminate foul odors, and
·
Cost no money to operate
The more air is diffused into small
bubbles, the more efficiently the oxygen from those bubbles is diffused into the
ponds, lakes or reservoirs. It is also important to understand that colder
water absorbs oxygen much more readily than warmer water; therefore aeration
during warmer months is much more critical in keeping a pond from going into an
oxygen-depleted state.
Benefits of aeration
It’s equally important to note that although
the mechanical and chemical treatments are effective, they are only effective
for short periods. You can extend that time and maximize treatment costs by
aerating your pond. An electric, windmill, or solar type aerator will help
increase the needed oxygen in your pond, lake, or reservoir.
Windmill Aeration
From small farm ponds to multi-acre farm ponds,
especially remote ones, WINDMILLS have proven to be a good alternative energy
choice for aeration. Proper aeration of a pond can prevent stagnation, improve
the unsightly appearances, and eliminate unpleasant odors. It also aids in the
release of sediment-bound nutrients, and reduces algae blooms. In addition,
aeration will help accelerate the decomposition of organic material, and reduce
oxygen-related stress on fish. This is particularly critical during the summer
months, when water temperatures are high and oxygen levels low. It is also
important, but not as critical in winter months when oxygen levels are higher,
because its keeps the pond from totally freezing which is critical to the
overall health of the fish and the pond.
 Stagnant
water is not only an environmental concern to the health of the fish; it
also provides an excellent breeding ground for mosquitoes. More and more pond
owners, with remote ponds are turning to windmill aeration systems as a cost
effective and energy efficient alternative of keeping ponds from stagnating,
thereby reducing the risk of the West Nile virus and other diseases. Mosquitoes
prefer stagnant, nutrient rich water and temporary wet areas for breeding.
Studies show that aeration is an extremely effective way to keep mosquitoes from
breeding in water.

Capacity
Up
to 1.5 CFM (cubic feet of air per min.)
Turbine Type
Upwind
Rotor Diameter
65"
Swept Area
19.63 sq. ft.
Blade Design
Proprietary
Transmission
Direct drive
Stroke
0.5"
Over-speed Protection
Automatic
Foundation
3 ground rods; 1" diameter
pipe, 4' long
Blades
Large 72" Diameter fan
wheel. Twelve blades are tapered and get wider at the outer tips, and also
change pitch. This allows blade assembly to start turning at low wind speeds
and also develop high power in strong winds.
Hub
Welded steel hub is
completely assembled. The blades can easily be attached to the hub. Hub
securely attaches to shaft with 2 set screws tightened down to flat spots on the
shaft, and a bolt and washer in the end of the shaft prevents the fan wheel from
ever coming off.
Over speed protection:
The tail design keeps the
windmill facing directly into the wind, until wind speeds reach 30 mph. At this
time the tail forces the fan wheel to turn 12 to 15 degrees away from the direct
wind so that it cannot over speed. It's all-automatic.
Compressor
Direct
drive diaphragm pump with 1/2" stroke. The compressor is made up of a
precision-machined diaphragm push plate, 2 valve retainers, and a cast iron
bearing holder on camshaft. (No welds to break or warping of steel due to
welding.)
Diaphragm:
The diaphragm is reinforced
neoprene die cut for accuracy and longevity. The piston and diaphragm assembly
is 60% larger than others, and with the added power of a 72" blade assembly,
will pump 60% more air into your water.
Intake Air:
All intake air is filtered
through a re-cleanable filter.
Crankshaft and Bearings:
The crankshaft is made of
high strength 1045 TGP Steel. Bearings are permanently grease sealed, and are
designed for heavy load capacity.
Head Assembly:
The air compressor, blade
assembly, and tail assembly, is properly balanced over the top of the tower.
This allows the head assembly to easily find the direction of the wind.
Freeze Control
The Optional Freeze Control
unit is designed to monitor pressure in the airline. On cold days with high
humidity it is possible to get line blockage due to the moisture freezing within
the line. When this occurs the Freeze Control will automatically release an
alcohol agent in the line to thaw it. The Freeze Control allows for aeration in
the winter and also keeps excessive pressure from building up in the compressor,
possibly causing damage to bearings, etc.
Towers:
The
tower design is very similar to the old style water pump windmills. It is made
of galvanized steel angles and "x" bracing. It has 4 legs. This means it
covers more square feet of area than a tower with 3 legs, and also it has 4
anchor stakes instead of only 3. This all adds up to more stability.
Available in heights of 12,
16, and 20 feet.
Anchor Stakes:
At the bottom of each tower leg is a 6-bolt
anchor stake clamp. The anchor stakes are 1" steel tubes pinched on both ends.
The anchor stakes slide down through the clamps as you drive them into the
ground. This is a good anchoring system and also allows you to level your tower
as you tighten the clamps. Other anchoring systems can be used at your own
discretion.
Maintenance:
Very low maintenance is
required. This complete windmill was designed with assembly and maintenance in
mind.
Warranty:
We are so confident in this
design that we have included a 3 year limited warranty.
SOLAR ADDITION TO WINDMILL
Any of the above windmills can be
equipped with a supplemental solar compressor system that acts to supplement the
windmill when the wind is not blowing. The solar system is designed to operate
during the dog days of summer or whenever the sun is shining, but the wind is
not as active. It is not meant to replace the windmill, but rather support it.
