Primus Wind Power Air 40 + Control Panel + 45' Tower Kit



The proven choice for remote energy

AIR 40 is the premier micro-wind turbine for land-based applications. It operates efficiently across a wide-range of wind speeds, providing energy for telecom, water pumping, lighting, SCADA, off-grid homes, or other low energy demand battery charging applications. The AIR 40 is ideal for pairing with solar to offset seasonal variation, delivering more consistent energy.
