Spiral wind turbine (vertical axis)

1. better able to harvest turbulent air flow found around buildings and other structures.
2. Ideal for both rural and urban applications, including roof top installations. Depending on the shape of the roof, the wind flow over the roof can be concentrated, leading to an increased energy output.
3. Simple to install and maintain.

4.Low start up speed, compact, light, beautiful and with little vibration;
5.Easy installation,flange connection;
6.Blades using aluminum alloy, spray-paint and oxidation treatment of the blades surface, strengthen the anti-corrosion level, more beautiful and durable, Color optional;
7.Patented permanent magnet ac generator with special stator (maglev generator), effectively reduce torque, make only 1/3 torque of ordinary generator, well match the wind wheel and generator, and ensure the performance of whole system.

8.Rich colors: white, orange, yellow, blue, green, mixed, customized.
9.One-piece Blade design ensures higher rotational stability.
10. Coreless PMG or maglev provides lower start torque/wind speed and longer service life.
11.Maximum RPM protection. No higher than 300RPM, regardless of the wind speed.
12.Easy installation, Screw & Play.
13. 48V could be customized.
14.Design service life 10~15 years.
