The main function of the Air Filter is: air exchange purification, removing the dust particles inside the new gas, which is characterized by low dust concentration in the air, fine particles, and high purification efficiency.
Main frame materials are: paper, aluminum alloy, galvanized steel and so on.
The main filter materials are: glass fiber filter cotton, activated carbon filter cotton, synthetic fiber filter cotton, non-woven filter cotton and so on.
1
Fiberglass filter cotton
Glass fiber filter cotton is mainly made of glass fiber of different thickness and length by special processing technology. Glass fiber with its stable performance, high temperature resistance, high efficiency, large capacity, long service life and so on. And in some special circumstances, only wave lines can do the job. Widely used in the general ventilation system of the initial effect filter, high temperature filter and high efficiency filter, the air filtration requirements of high places and environments.

Activated carbon filter cotton
Activated carbon is characterized by the removal of odor in the air. Activated carbon filter cotton refers to synthetic fiber after carbon impregnation and glue treatment. Because the role of activated carbon is to remove odor, there is no emphasis on filtration efficiency. In use. Generally, it must be combined with the use of independent primary and medium efficiency filters.

Synthetic fiber filter cotton
In the general filtration environment, it can fully replace non-woven fabrics and glass fiber covering coarse, medium and efficient full series of filtration products, which is an emerging filtration material and the main development direction of filter materials in the future. Compared with other filter materials of the same level, it has the advantages of low resistance, light weight, large capacity, environmental protection (can be incinerated) and moderate price. Use (polyester fibre) as the main raw material, abbreviation abbreviation: PET, polyester fiber is made of polyethylene terephthalate, also known as synthetic fiber or polyester. Polyester has excellent crease resistance, elasticity and dimensional stability, good electrical insulation, sun resistance, friction resistance, no mold and no decay, good chemical agent resistance, weak acid and weak base resistance. The industry name is: chemical fiber, chemical fiber has large chemical fiber and small chemical fiber

Non-woven filter cotton
The scientific name polyester fiber, commonly known as non-woven fabric, non-woven fabric has the technical characteristics of wide use, technical maturity, good stability, etc., is the typical filter material of China's current early and medium efficiency plate and bag filter. Compared with other filter materials of the same grade, it has the advantages of stable quality, large dust tolerance, strong moisture resistance, long service life, economic and durable. Non-woven fabrics are also the earliest application of filter materials, mature technology development, low production costs, in recent years due to the continuous progress of technology, the emergence of composite non-woven fabrics greatly improve the image of cheap low-grade non-woven fabrics, in efficiency has been able to achieve sub-efficiency. At the same time, the composite non-woven filter material can also be used for filtration in places with relatively high air cleanliness requirements.
