What about Lancer's fresh air system? What is the general level of fresh air system?

Lanshe fresh air system 1970 was established in France, and 1975 entered the field of fresh air in Europe. Since entering China in 2003, it has obtained many national patents in 2009. In the same year, it became the main maker of national living standards in the same industry, and has cooperated with many real estate developers to provide ventilation systems for many real estate projects in China. Its comprehensive performance is in the forefront of the industry, and Lanshe fresh air system is worth buying.

According to the product catalogue of Lanshe fresh air system above official website, China, at present, Lanshe fresh air series products include domestic central fresh air series and commercial central fresh air series, and even domestic central fresh air series products can be divided into: total heat dehumidification new fan, cabinet heat exchange dehumidification new fan, total heat exchange new fan, villa type total heat exchange new fan, through-wall dehumidification new fan, single/multi-point delivery (exhaust) fan and Zhenzhi. In order to show it more concretely, we selected a new fan with the model of ERV250/S/L as a specific product, and took a look at the fresh air system of Lanshe from the aspects of filtration system composition, purification capacity, air volume and noise, power and energy consumption.

More efficient

low power consumption

The overall performance has no outstanding characteristics on average.

According to the composition of the fresh air system, there are two kinds of two-way flow and one-way flow. The two-way fresh air system adopts active suction and exhaust, which will have excellent ventilation efficiency and indoor and outdoor temperature, but it needs two large ventilation pipes, which is not suitable for families living in buildings. In addition, it needs to be laid in advance before decoration, but it is recommended to choose two-way flow products, which has high ventilation efficiency.

Because the main purpose of fresh air system is ventilation, not filtration; This product can reach 95% of the once-through efficiency of PM2.5 under the nominal parameters, and the purification efficiency is still good. The air volume is determined according to the length of the ventilation duct installed and designed in the home and home area. Finally, in terms of power consumption, the maximum power consumption of 1 18W is satisfactory.

To sum up, Lanshe has many years of experience in designing and manufacturing fresh air systems, so it is recommended to purchase fresh air systems from Lanshe. However, it is best to consult the local installation company to check the installation qualification before buying, because the fresh air system needs to be installed simultaneously during home decoration, and the design and installation of the fresh air system is very important.
