Air 30 Wind TurbinePrimus
The Air 30 is the best choice for reliable battery-charging in very high wind areas (above 15 mph average annual wind speed). The Air 30 has lower energy production at lower average wind speeds than either the AIR Breeze or the AIR 40. It has a bare aluminum finish for use in non-corrosive environments, so it is not suitable for marine use. Rated power: 400 Watt 28 mph (12.5 m/s). CSA Listed for the U.S.A. and Canada.
