1: Available specifications for this product: 100mm, 110mm, 150mm, 160mm, 200mm, 300mm, 400mm, 450mm, 500mm, 600mm, 800mm (bottom diameter)

2: The product can be selected as a pre-assembled finished product or as separate parts for self-assembly.

3: The greatest advantage is that it does not require an external power source; it operates automatically relying on natural wind and air pressure differences, achieving ventilation and air exchange. Over time, it can save a significant amount on electricity costs, demonstrating considerable energy-saving effects. It is especially suitable for places where cost sensitivity is high, ventilation requirements are not overly demanding, but continuous air exchange is needed.

4: Through reasonable turbine blade design and overall structural optimization, it effectively expels indoor stale air, heat, humidity, etc., while introducing fresh air, improving indoor air quality, regulating indoor temperature and humidity, and creating a comfortable indoor environment.
