AIR 40 Wind Turbine by Primus Windpower

The AIR 40 off grid wind turbine is the land version of the AIR Breeze marine wind turbine.

We recommend the AIR 40 domestic wind turbine for small battery-charging applications: remote homes, telecom, industry, lighting and more. The AIR 40 is an ideal wind turbine for hybrid systems with solar to offset those cloudy or wintry periods.

AIR 40 is built and backed by the worldwide leader in small wind power. It has an advanced microprocessor for reliable energy production and an integrated overcharge protection which eliminates the need for an external charge controller or dump load.

The composite blades are designed for durability and optimum wind capture combined with high-quality, field tested components and quiet operation mean it will be suitable for most inland off grid systems.

The AIR 40 is lightweight and very easy to install.

The AIR 40 is for use in non-corrosive environments, so if the turbine is to be installed near the coast, then we recommend the AIR Breeze wind turbine as it has an anti saltwater corrosion coating.  Primus Windpower's AIR 30 wind turbine is more suitable for high wind locations.

 Although rated at only 160W the AIR Breeze and AIR 40 will produce approximately the same KWH power over a specific time as a 300-400W rated unit. This is because they are designed to produce power at the average wind range of 10-15mph and not just in strong winds. So over a month the unit will probably put out more KWH than some higher power 'rated' turbines that need stronger winds to operate. Again you need to think carefully about which turbine model will best suit your purpose.
