Structure of high-quality
The strict ball-shape structure and the permanently lubricant upper and lower ball bearings ensure long life, no maintenance, no need to replace the parts. The United States UBC high-precision completely closed bearing systems provide absolute excellent quality assurance.
Precise operation device
High-precision completely closed bearings system, high heat-resistant synthetic lubricating oil and grease is the best lubricant for bearings which can self-lubricate permanently, without maintenance. It can also self-operate even if the wind speed is less than 2Km of the breeze.
Environmental protection ventilation
We used the natural wind-driven principles, not the motor power to avoid the cost of power. As the turbine ventilator continuously self-rotation, so there is no noise when runnin
