Founded in Zhejiang, Hangzhou Aopu Electric Appliance Co., Ltd. manufactured China's first bath bomb in 1993, and in 2003 with Zhejiang University professors jointly developed the first generation of integrated ceilings, in 2008 became the national standard formulation unit of integrated ceilings, more than 20 years has always focused on indoor air business, has obtained more than 150 national patents, more than 10 years to occupy the first place in the sales of bath bomb industry.
 
Although the ventilation fan of Aopu does not have the dominant position like the bath bomb industry, it should not be underestimated, with the technical support of Aopu in the ceiling industry, the ventilation fan products of Aopu have extremely excellent performance characteristics. Aopu's ventilation fans only do ceiling type, and most of them belong to integrated ceilings, its products use three-dimensional exhaust mode, the Archimedes air duct and airfoil blades are combined to increase air volume and suction, to achieve efficient ventilation. In addition, the industry's original wind guide swing blades and double twist line air ducts, some products with optical-grade LED lighting, and flat design of multi-ceiling installation methods are all unique advantages of Aopu ventilation fans.
 
In China, consumers who have high requirements for ventilation fans, but are discouraged by the price of bath bombs, are often keen to try Aopu's ceiling type, which not only has the multi-function of integrated ceiling, but also the price is not too high, usually between 400-800 yuan.
 
Compared with a variety of bath bombs and cool bomb products, Opple focuses on BP-D in the field of ventilation fans, and has 5 products according to different specifications and installation methods. BP-D adopts ball bearing motor, combined with the design of double twisted air duct and unequal distance blades, to achieve the goal of large air volume and low noise. Among them, BP16-25D is the best-selling representative of Opple, different from the general grid panel, 25D adopts a smooth flat panel, the corners of the panel are rounded, to avoid excessive sharpness during installation and cause skin damage. The most attractive thing is that when working, the panel extends down and is suspended, and the indoor air enters the ventilation fan from all around the panel, and the ventilation is realized through the fan agitation, and its price is close to 400 yuan.
 
It is worth mentioning that most of the products are sent in double-layer packaging, with high hardness of outer box materials, and eight foot pads between the inner and outer boxes to cushion external pressure and ensure the safety of transportation. In addition, the installation cost of the Aopu ventilation fan is 60 yuan, which is slightly higher than the installation cost of other brands.
