400W Wind Generator
Marine Version
AIR-X Wind Module Introducing the latest evolution in small wind
turbines. The AIR-X builds upon what made AIR the world's #1 selling small wind turbine
with new technology previously found only in today's state-of-the-art mega-watt-class wind
turbines.
All of these features are primarily found within the body of the
turbine. The new microprocessor based speed control results in increased performance,
improved battery charging capability and the reduction of “flutter” noise from
the machine. The controller allows for peak-power tracking of the wind by optimizing the
alternator's output on all points of the cubic curve and then efficiently delivers the
energy to the battery. The turbine’s smart controller allows it to actually control
blade rotation speed thus eliminating the buzzing noise commonly found with the AIR 403
and 303 in high winds. Furthermore, a new series of carbon-reinforced blades with a
modified pitch angle further increases power production.
The new electronics are a considerable improvement over the AIR 403
controller that consists of diode-rectification and a simple off/off voltage switch.
Much Lower Noise: Previous AIR wind modules relied
on their aero-elastic blade design for protection in high winds, causing loud flutter
noise in winds above 35 mph (16 m/s). AIR-X’s circuit monitors the wind speed and
electronically slows the blades as it reaches its rated output preventing it from going
into flutter. This results in a much quieter wind turbine. In high winds, the AIR-X will
continue to produce power at a reduced level until the wind decreases, at which point
maximum output will resume. The Benefit: Quieter and neighbor friendly operation.
Improved battery charging: Previous AIR designs
required 300-400 amp hour battery banks so the trickle charge of the wind turbine could be
adequately absorbed. The AIR-X’s charge controller periodically stops charging, reads
the battery voltage, compares it to the voltage setting and if the battery is charged, it
completely shuts off all current going to the battery. This function is performed within a
few milliseconds. The closer the battery is to reaching its full state of charge, the more
often the AIR-X’s circuit repeats this action. This means any size battery bank from
25 to 25,000 amp hours or higher can be charged safely. When the battery has reached its
charged state, the AIR-X will slow to an almost complete stop. Only when the battery has
dropped below its voltage set point will it startup and resume charging. The Benefit:
Extended battery life, no overcharging.

Lower stress design: AIR-X limits power on the
input side of the electronics by controlling the torque from the blades. The power no
longer has to be dissipated by the electronics resulting in lower stress on the circuit,
bearings and other materials. Furthermore, stress on wind turbines occurs primarily in
high winds. Under these conditions, the electronic stall design reduces the blade speed to
600 rpm, thereby significantly reducing turbine and tower loading while still producing
power. The Benefit: Greater confidence in turbine operation in high wind conditions
without manually operating the stop switch. Note: A manual stop switch control is an
available option for the AIR-X.
Improved resistance to the effects of the sun, wind and
water: AIR-X marine has vastly improved body preparation and applications of the
marine paint during manufacture, ensuring durable powdercoat protection of the body and
internal components, even when subjected tot he most extreme sun, wind and water
conditions.
Design changes are primarily found within the body of the
turbine:
 | New microprocessor-based controller. |
|
| New "wave washer" combined with looser bearing-to-body tolerances are
incorporated into the face bearing set. This results in lower compression on the
bearing/race, with quieter running and lower startup speed. It also lowers stress on the
bearings and shaft when subject to twisting forces during normal operation. |
|
| New series of carbon reinforced blades. |
|
| More robust tower clamp and yaw assembly for stronger and more secure tower
mounting. |
|
| Improved powdercoating protection, as the body is acid etched and treated with
alodine before powdercoating with a UV resistant marine paint. |
|
| All hardware is a marine grade stainless steel. |
|
| Assembly includes "Tef-gel" compound to resist corrosive activity
between dissimilar metals like stainless steel and aluminum. |
|
| Body and electronics are completely sealed for prevention of water ingress, even
under brief immersion conditions. |
