Performance characteristics

1. Environmental protection: no electricity needed, continuous operation, energy efficient, no noise, no spark, with explosion-proof.

2. Weatherproof features: arc-shaped blades, there are gaps between the blades, when rotating, the blades complement each other to fill the gaps, a large amount of rain are thrown out round the pitch line, a small amount of rain flow to the roof, it will not flow into the turbine, in the meantime the rotating turbine push out the air from the blade gap, block the rain.

3. Operating device: The use of high-tech ball bearings, this bearing is completely closed, and always self-lubricating, so that it can rotate in less than 3.2Km/h speed.

4. Dust proof: Turbine fan is in a 24-hour non-stop rotation, dust is not easy to attach, and it is easy to clean.

5 Using life: the general using life is more than 15 years.

6 wide range of applications: only need a breeze wind of 0.2m / s breeze, or indoor and outdoor temperature difference of 0.5 ℃ or more can make it rotate continuously, flat roof is OK, inclined roof (less than  31.5 °) is also ok, adjust the turbine axis to vertical.
