AIR 40 is the best choice to provide energy for off-grid homes, water
pumping, lighting, telecom and anywhere you need electricity and have
wind. AIR 40’s optimized electronic controls deliver energy quietly and
efficiently. Extensive third party testing and certification shows more
consistent output than the competition. AIR 40 is part of the latest
generation of AIR products—the world’s best-selling wind turbines—with
more than 135,000 units sold in more than 120 countries
Proven, solid performance
We recommend AIR 40 for small battery-charging applications: remote
homes, telecom, industry, lighting and more. The AIR 40 is an ideal
wind turbine for hybrid systems with solar to offset those cloudy or
wintery periods. Not for use in marine environments. AIR 40 is built
and backed by the worldwide leader in small wind.
