Southwest Windpower Air 403 Marine 24V 400W Wind Turbine
AIR marine starts producing power at 6 knots and will produce over 400 watts (28 amps) in a 24-knot wind. The new AIR's output is truly impressive. In only ten knots of wind, the turbine will deliver a consistent 2-3 amps and over 8 amps in only 15 knots. Its lightweight and compact design and integrated electronics make it perfect for sailboats of all sizes.
AIR marine's cast aluminum body and corrosion-resistant powder coated finish offer the cruiser the highest possible quality and reliability in wind turbine design. When taking that next extended voyage, you can be assured the AIR marine will keep your batteries charged.
AIR marine Thousands of satisfied customers now own AIR marines which has made it the best selling wind turbine of all time.

AIR is the number one selling battery charging wind turbine in the world. AIR brings together advanced brush-less alternator technology, state-of the-art carbon composite rotor blades, and exclusive built-in voltage regulation all in an elegant cast aluminum body.
BLADES: The AIR's blades are made of carbon fiber reinforced composite that twists as the turbine reaches its rated output. This twisting effect changes the shape of the blade, causing it to go into stall mode. This limits the RPM of the alternator, preventing damage in high winds.
ALTERNATOR: The AIR's alternator is optimized to match as close as possible the energy available in the wind. It is constructed with Neodymium Iron Boron permanent magnets and is brush-less for superior performance and maintenance-free operation.
REGULATION & CONTROL ELECTRONICS: The electronics performs several functions to assure maximum output and safety for the user. The control electronics maintains a load on the alternator at all times to make sure that the turbine never over speeds, regardless of the condition of the battery. As the battery is charged, the sophisticated regulator periodically checks the line, correcting for voltage loss and monitoring charge rate. Once the battery has reached its optimum charge level the regulator shuts the current off preventing the battery from being overcharged, then the blades slow to a silent spin, also preserving bearing life. When the batteries again need charging, the turbine's electronics automatically release the brake and allow the amps to flow!
In just over four years, over 20,000 AIR's have been sold, making it the number one selling turbine in the world. This means that when buying an AIR, your buying confidence.
