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.
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-Xs
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-Xs 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-Xs 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,
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.
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.

More robust tower clamp and yaw
assembly for stronger and more secure tower mounting.
