48V AIR 40kWh Wind Turbine Primus Wind Power


48V Air 40 Wind Turbine Primus Wind Power


48V AIR 40kWh Wind Turbine

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.

  • ¬†Advanced microprocessor technology for superior performance and high wind protection without mechanical braking.
  • Blades designed for quieter operation, durability and optimum energy capture in most wind speeds.
  • Lightweight design is simple and easy-to-install; integrated controller for plug-and-play operation.
  • Pair with solar PV for redundant energy production year-round.
  • Produces 40 kWh of energy per month generating energy in a wide range of wind speeds.
