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 speed to 600 rpm, thereby significantly reducing turbine and tower loading.  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 powder-coat 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 powder-coating protection, as the body is acid etched and  treated with alodine before powder-coating 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.
