Airdolphin Mark-Zero/Pro

エアドルフィン Mark-Zero/Pro

These high-performance small wind turbines were created through the combined talent from the Japanese government, industry, and academia. The first model was the Airdolphin Mark-Zero by Zephyr. Airdolphin Pro followed, a model developed as an innovative independent power source targeted for the telecom market. It reduces various electric generation costs for remote base stations such as fuel costs, and has attracted the attention of mobile operators around the world.
