With the serious process of modern industrialization, air pollution, coupled with more and more complex due to the housing structure, increasingly tight sealed room, interior decoration pollution, furniture, office environment, more and more impact on indoor air quality, so the interior "Hardware" Although more and more "luxurious", but indoor air quality has become increasingly "lower", resulting in a long time often appear strange or body work indoors or people living in the spirit of the new air system is getting worse basement prices, so People gradually began to pay attention to indoor air quality improvement. In addition to the tightness is better or not easily ventilated place, ordinary family living also now choose to install ventilation systems, and ventilation systems in the more prominent is the new air system. Hazardous substances construction, decoration, furniture, decoration and office equipment is a major cause of the release of indoor pollution. Plus summer and winter people rely more on air conditioning to cool and indoor heating, indoor ventilation is poor, indoor harmful gas is not released and the replacement of harmful gases continue to accumulate in the basement air system filtration, concentration continuously increased, leading to indoor air quality worse, people feel sleepy, fatigue, chest tightness, and susceptible to decreased productivity, which is the World Health Organization naming "and state building syndrome", also known as "air-conditioned." The root of these difficulties is the lack of fresh air. Use fresh air ventilator replace indoor air, keep indoor air clean, can solve these problems. Therefore basement air system, new wind ventilators is also a "health" products. PM2.5 purification tank 1, built-in triple filtration system 2, high PM2.5 purification efficiency 3, dock and heat exchange equipment, expand the existing capabilities of the device in the basement of new wind ventilators, air purification and more flexible choice of security in the inlet box place, with a total heat exchanger, two-way flow of new fans supporting the use of outdoor air can effectively filter harmful substances. Purge tank has a dual filtering function, a coarse filter and a fine filter, coarse filter can filter out the dust, and other compounds, some of the outdoor harmful objects we can see with your eyes. Fine filter can filter out carbon monoxide, carbon dioxide, formaldehyde, benzene and other outdoor something we can not see with the eyes of harmful gases. Outdoor turbid air purification filter impurities through the new bellows through filtered fresh air through the total heat exchanger, two-way flow of new fans to be exchanged, so the room can stay healthy fresh air.
