The AIR is by far the world’s number one selling small wind turbine.  In late 2001 Southwest Windpower introduced an entirely new level of technology which previously was only found in today's state-of-the-art mega-watt-class wind turbines.

The AIR-X incorporates a new microprocessor based technology that results in increased performance, improved battery charging capability, greater reliability and the reduction of “flutter” noise from the machine.
