Recommended series/models: Smarto.H series, Thino series
 
Founded in 1932 in Wisconsin, USA, Braun has been committed to the development and manufacturing of products in the field of indoor air quality for 80 years, and has now become the chief ventilation brand in North America, and is a recognized leader in the field of air replacement in the world.
 
At present, the central fresh air system promoted by Braun is a full heat exchange type, different from many brands on the parameters of the full heat exchanger, Braun and Panasonic are also quite generous to list the energy efficiency, heat exchange rate and enthalpy exchange rate is the most important parameter of the full heat exchange core, but also the technical barriers of the fresh air system industry, Braun selects high specific heat capacity, and has hydrophilic characteristics of polymer fiber as the base material of the full heat exchanger, with excellent temperature and humidity regulation ability, under the air volume of 280m³/h, The highest enthalpy exchange rate can reach 73%, the comprehensive performance is comparable to Panasonic's "Suzi", and the fiber material has excellent characteristics of fire and mildew resistance compared with traditional paper materials.
 
Smarto.H series and Thino series are the two major series of central fresh air system on sale at Byrun, both of which are imported from the original and positioned in the high-end market, and the price of the main engine alone starts from 13,000 yuan and can reach up to 35,000 yuan. The Naming of Smarto.H and Thino's products is quite regular, such as Smart 3.0H means that its air volume is 300m³/h, and the same is true of Thino, the main difference between the two series is in the filtration performance, Smart.H series models all have H12 HEPA filters, while Thino only has G4 primary filters.
 
In fact, the main function of the central fresh air system at the beginning of the design is ventilation, but Chinese consumers have a more practical demand for haze removal, in response to this situation, Braun launched a filter box device connected with the fresh fan, different from Honeywell's electronic purification box, Braun uses a pure physical filtration method of five-stage filter, PM2.5 removal rate is as high as 99.7%, the volume of the filter element in the filter box is generally larger, and the continuous working life is stronger, but it still needs to be replaced regularly. The price of the entire set of filters is also on the high side.
 
The workmanship and materials of Bailang are also quite solid, the shell of the host is made of metal plates, the workmanship is tight, giving consumers a sense of solidity, and the power source is built into the German EBM customized motor, which lays a solid foundation for the fresh air performance and continuous work reliability of the product, combined with reasonable air duct design, the static pressure performance of the main engine of the Bailang fresh air system is excellent, taking Smarto 3.0H, which is the most popular in the family, as an example, its maximum static pressure is as high as 270Pa, which is much higher than the wind pressure of 100Pa of conventional competing products. It is able to deliver fresh air to greater distances.
 
In addition, the internal insulation structure developed by Braun is also excellent, which is called the "room shield defrost design", which covers the surface of the full heat exchanger with an insulation layer, and with excellent sealing workmanship, it can protect the fresh air system from the temperature range of -30 °C to 40 °C, which is especially suitable for the domestic environment with huge climate differences between the north and the south.
 
Compared with Panasonic's strong domestic sales channels, Braun is much more low-key, and the coverage of offline services needs to be improved, which affects Byrun's marketing promotion and consumers' purchase choices to a certain extent.
