Wind Generators from Southwest Windpower
Air 403 (Land)
$515.00
In 1996, the introduction of the AIR-303 revolutionized the battery charging wind turbine market. People quickly began to see that wind was as easy to use as Photovoltaics. And now, over 30,000 turbines later, the new 403 has once again rewritten the history books as it became the best selling wind turbine in the world. Still priced about the same as a photovoltaic module, an AIR is capable of producing more than seven times the energy! |
| Maintenance-free
performance, easy installation, and high output make AIR ideal for virtually
any remote battery charging application. The AIR is designed to be used in combination with photovoltaic modules to balance system energy output during times of seasonal fluctuations. No room for a tower? AIR's compact design make it ideal for roof top mounting. Check out the Tower Kits Page for more information. |

| BLADES: The AIR's blades are made of a 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 stall, limiting the RPM of the alternator protecting the
AIR from damage in high winds. ALTERNATOR: The AIR's brush-less alternator is optimized to match as close as
possible to the cubic energy in the wind. It is constructed with Neodymium Iron Boron
permanent magnets for superior performance and maintenance-free operation. REGULATION &
CONTROL ELECTRONICS: The electronics perform several functions
to assure maximum output and safety for the user. The control electronics maintain a load
on the alternator at all times to insure 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 and slowing the blades to a silent spin. |
