Formerly made by Southwest Windpower, the AIR 40 is now made in the USA by Primus Windpower in Colorado. The AIR 40 is essentially a land version of the AIR BREEZE.
The AIR 40 is designed to deliver quiet operation in low to moderate wind environments. Yet works on a wide range of wind speeds. The blades are specifically designed for lower sound emissions.
The AIR 40 is an ideal turbine for hybrid combinations with solar PV.
Use it for SCADA, telecom, security, cathodic protection, oil & gas, railroad, lighting systems, coastal applications, off-grid homes, cabins -- you name it.
Not typically used in marine environments.
High-quality, third-party tested components for reliability and safety.
Advanced microprocessor technology for superior performance and high wind protection without mechanical braking.
Lightweight design is simple and easy-to-install; integrated power electronics for plug-and-play operation.
Microprocessor-based smart control. Which means internally regulated and does not require a separate controller.
Produces 40 kWh of energy a month* for land-based (ave 13 mph).
