Several layers of filtration in the fresh air system

2018-10-23

In addition to ventilation and ventilation, the most important function of the fresh air system is to filter the pollutants in the air. Therefore, the filter of the fresh air system is the most important part of the whole system. In the fresh air system, the primary, intermediate and high efficiency filters are generally not used alone, but in combination with two or three. A fresh air system with more than two layers of filters can achieve better air filtration.

The general fresh air system filter can be divided into three levels: the primary filter, the medium filter and the high efficiency filter.

The fresh air system generally has three layers of filters, which are primary, medium and high efficiency filters.

1. Primary effect filter: It is made of non-woven filter material, which is mainly folded. After the folded part is unfolded, the area is enlarged several times and the filter area is large enough. As a primary filter, it can effectively filter large particles of dust and insects in the air into the body;

2, activated carbon filter: with activated carbon efficient adsorption performance, can be used for air purification, removal of volatile organic compounds such as formaldehyde, odor and other air pollutants. The bulk density is small, the surface area is large, and the adsorption efficiency is high.

3, high-efficiency filter: HEPA divided into PP filter paper, glass fiber, composite PPPET filter paper, melt-blown polyester non-woven fabric and melt-blown glass fiber five materials. Features: large wind resistance, large dust holding capacity, high filtration precision, can be processed into various sizes and shapes according to customer needs, suitable for different models. HEPA filter, HEPA is an abbreviation for high efficiency air, so it is a purifier that can effectively filter out ultrafine particles of air. HEPA Chinese means high-efficiency air filter, which meets the HEPA standard filter. The efficiency of 0.1 micron and 0.3 micron is 99.7%. The HEPA net is characterized by air passing through, but fine particles cannot pass.

In the fresh air system, the primary, intermediate and high efficiency filters are generally not used alone, but in combination with two or three. A fresh air system with more than two layers of filters can achieve better air filtration.
