Non-woven filter: the scientific name polyester fiber, commonly known as non-woven fabric. Non-woven fabric has the technical characteristics of wide application, complex technology and good stability. It is a typical filter material for primary, intermediate and bag filters in China. The manufacturing process is melt-blown, spiny, spunbond and other processes made by multiple processes.

Compared with other filter materials of the same level, it has the advantages of stable quality, large dust removal, strong moisture resistance, long service life and economy. Non-woven fabrics are also an earlier filter material. In recent years, due to the continuous development of technology, the emergence of composite non-woven fabrics has greatly improved the low-cost image of non-woven fabrics, and reached low efficiency in power.

Synthetic fiber filter: in the general filtration environment, it can completely replace non-woven fabrics and glass fibers, covering a full range of coarse, medium and efficient filtration products, which is a new filtration data and the main development direction of future filtration data. Compared with other filter materials of the same level, it has the advantages of low resistance, light weight, large capacity, environmental protection (flammable), moderate price and so on.

The honeycomb activated carbon filter is made of powdered activated carbon, and its carbon content is 35%- 50% about 10%. The air resistance is small, the energy consumption is low, can deodorize, deodorize and purify the environment under a certain air volume, and has good purification effect. In the application. It is generally necessary to use an independent junior high stainless steel filter.
