Primus Wind Power AIR 40


  • Best for low wind speeds
  • Built in charge controller
  • Available in 12, 24, and 48 volt
  • Description

    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 engineered to deliver quiet operation in low to moderate wind environments, but the design works on a wide range of wind speeds.

    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. NOTE: This model is 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. The turbine is internally regulated and does not require a separate controller.
    • Produces 40 kWh of energy a month* at an average wind speed of 13 mph
