Air filter media

Product Details

What are the filter material classifications of air filters? Next, Mia Ruan from Guangzhou Xincheng New Materials Co., Ltd. will explain to you: The main function of the air filter is to purify the air and remove the dust particles in the new air. Fine, the required purification is high.

The main frame materials are: paper, aluminum alloy, galvanized steel plate, etc.

The main filter materials are: glass fiber filter cotton, activated carbon filter cotton, synthetic fiber filter cotton, non-woven filter cotton, etc.

1. Glass fiber filter cotton

Glass fiber filter cotton is mainly made of glass fibers of various thicknesses and lengths through special processing technology. Glass fiber has the characteristics of stable performance, high temperature resistance, high efficiency, large capacity, and long service life. And in some special environments, only glass fiber can be competent. It is widely used in primary filter and high temperature resistant filter of general ventilation system, in places and environments with high air filtration requirements.

2. Activated carbon filter cotton

The characteristic of activated carbon is to remove the odor in the air. Activated carbon filter cotton means that the synthetic fibers are treated with carbon impregnation and glue. Because the function of activated carbon is to remove odors, the filtration efficiency is not emphasized. in use. Generally, it must be used with separate primary and medium efficiency filters.

3. Synthetic fiber filter cotton

In general filtration environment, it can replace non-woven fabrics and glass fiber covering a full range of filtration products, including coarse, medium and high. It is an emerging filter 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. Using (polyester fiber) as the main raw material, abbreviated as PET, polyester fiber is made of polyethylene terephthalate, also known as synthetic fiber or polyester. Polyester has excellent wrinkle resistance, elasticity and dimensional stability, good electrical insulation properties, sunlight resistance, friction resistance, mildew and moth resistance, good chemical resistance, weak acid and weak alkali resistance. The industry name is: chemical fiber, chemical fiber is divided into large chemical fiber and small chemical fiber.

4. Non-woven filter cotton

The scientific name is polyester fiber, commonly known as non-woven fabric. Non-woven fabric has the technical characteristics of wide application, mature technology and good stability. It is the typical filter material of primary and medium efficiency plate and bag filters in my country. The production process is made of meltblown, acupuncture, spunlace, spunbond and other processes through multiple processes. Compared with other filter materials of the same level, it has stable quality, larger dust holding capacity, strong moisture resistance, long service life, economical and durable. Etc. Non-woven fabrics are also an early-applied filter material, with mature technology and low production costs. In recent years, due to the continuous progress of technology, the emergence of composite non-woven fabrics has greatly improved the cheap and low-end image of non-woven fabrics. At the same time, the composite non-woven filter material can also be used for filtration in places with relatively high air cleanliness requirements.
