The new Southwest Air-X 48 VDC is now more powerful, more reliable and quieter.

The new AIR-X isn't just an upgrade to the 403, it's an evolution in wind turbine design. It is the first small wind turbine with a micro-processor controller.

This machine starts producing power at half the RPM of the AIR 403, putting more power into your batteries. The new controller continuously adjusts the alternator loading to maximize alternator and blade efficiency at all wind speeds and all states of battery charge.

And now there is no more prop flutter noise in high winds. The new AIR-X can control RPM to prevent blade flutter in high winds. That means much quieter operation in all wind conditions.
