Speaking of fresh air fans, most young people may know that many families have given up air purifiers and installed domestic fresh air fans, and the coverage is getting higher and higher. Whether it is for commercial applications or household use, why do most people choose domestic fresh air fans?

The household fresh air fan is simply to purify the air quality in a certain space. It can't guarantee the circulation of air and fill in fresh air, but the purified fresh air fan is different. The fresh air fan can ensure the circulation of air. According to the centrifugal fan, the fresh air outside is sucked in, and according to the filter and heat exchanger core, the purified air with high oxygen content is discharged into the room, The dirty air with insufficient oxygen content and high carbon dioxide in the room is discharged outdoors according to the centrifugal fan, and then the air circulation and circulation system is generated to ensure the freshness and tidiness of the air in the room, which is why the fresh air fan is popular now.

At present, there are thousands of new wind manufacturers on the market, and the goods produced by each manufacturer are mixed. If you want to find that kind of professional manufacturer, which has its own production place, rather than that kind of production. Agents or engineering companies with time can visit and inspect the production line to see whether it is manufactured in strict accordance with the specifications. Some manufacturers have low direct sales, but the internal structure of the goods is shoddy, It is also necessary to understand the high purification efficiency of the purification fresh air fan. It is necessary to understand the filter screen level of the equipment. Sometimes, it is not the more filter screens, the better. More filter screens will aggravate the energy consumption of the fresh air fan, but it is not very good. The key is to see the actual effect of the filter screen. From a comprehensive point of view, it is not a difficult problem to choose a good fresh air system manufacturer. As long as everything is investigated and careful, it will not be compromised.
