Since 1992, Ludaofeng has entered the ventilation industry, and has established a research and development laboratory for wind tunnels, enthalpy difference, noise and other products, with more than 2,000 kinds of ventilation products, and is one of the drafting units of the relevant national standards in the ventilation fan industry. Ludaofeng's main fan products, industrial fan technology and motor manufacturing technology with large air volume are more prominent, and small household appliances such as household ventilation fan products are slightly mediocre.
 
The ceiling-mounted ventilation fans of Green Island Wind mostly use fully enclosed boxes, metal wind wheels, and metal panels to ensure protective performance. The all-metal series optimizes the air outlet interface and adopts a snap-on structure, which is stable and durable, and can prevent the airflow from being reversed; At the same time, this series is also one of the few products in China that adopts external rotor technology, which has a longer life than general motors and has obvious ventilation effect. The green island style window type does not have many design highlights, but the price is affordable and meets the needs of general family use.
 
APC-A, APC-D, APB-A, APB-B are the four window series of Green Island Wind. APC belongs to the light series, the appearance of the A type adopts a circular design, compared with the D type, the air volume is larger, and the noise is also greater, the price of the two series is less than 100 yuan, consumers can buy according to the size of the air volume. The APB series is a representative of large air volume, from 300m³/h to 1100m³/h, which is usually used in public places, among which type B has more mask structure than type A, and the price is about 100 yuan.
 
The BPT series belongs to the ceiling type, and there are many products under the series according to different specifications, and the price is between 100-300 yuan. Of course, there will be upgraded models in each series, and BPT10-22-H25L plays this role: this product uses double ball bearings, has a longer life than other models, and the body belongs to an ultra-thin design, weighing only 70% of the original series, and at the same time, it is also an integrated ceiling, with lighting function, and the most important thing is that the price is only 268 yuan, which is not higher because of these characteristics. If you are used to getting up at night to go to the bathroom and hate turning on the harsh incandescent lamp, then this product is the best choice.
 
The ventilation fan of Green Island Wind is decent, and high cost performance is its biggest advantage, so it is also one of the brands with the highest market share of ventilation fans in China.
