2022-09-17 Page view : 5 views

Glass fiber air filter paper is made of glass fiber as the main raw material by wet forming process. It has the characteristics of uniform fiber distribution, large dust capacity, small resistance and large strength. It is an ideal air filter material. Products are divided by filtration efficiency

For ventilation (ASHRAE); Medium and high efficiency (HEPA); Ultra efficient (ULPA)

Three series.

Glass fiber filter cloth is a kind of high temperature resistant filter material with reasonable structure and good performance. It not only has the advantages of high temperature resistance, corrosion resistance, dimensional stability, extremely small elongation and contraction rate and high strength of glass fiber fabric, but also has a single fiber, three-dimensional microporous structure, high porosity and low resistance to gas filtration. It is a high-speed and efficient high-temperature filtration material.

Compared with other high temperature resistant needled felts, it has the special advantages of low price, low running resistance, high filtering precision and higher temperature resistance. After being treated with polymer compounds, the filter felt has good corrosion resistance, bending resistance and wear resistance. High temperature resistant 260 ℃. Suitable for high temperature flue gas filtration in steel, metallurgy, carbon black, power generation, cement, chemical industry and other industries.

General purpose glass air filter paper and medium efficiency air glass fiber filter paper: mainly used for general air conditioning systems, gas turbines and air compressors. F6, F7, F8 and F9 are ultra-low resistance and large air volume air filter papers. They are produced by special glass fiber production process, auxiliary treatment on the fiber surface, and refined pulp preparation. The products have high efficiency, low resistance and folding resistance, especially in the low resistance of air resistance ≤ 12Pa. The filtration efficiency is 60-95%, and they have certain waterproof function. They can be used in places with high humidity.

Glass fiber filter paper (HEPA) for high-efficiency filters: mainly used for 10000-100000 level cleaning or workbench, nuclear power station exhaust, high-grade household vacuum cleaners, air purifiers, gas masks, etc. H10, H11, H12, H13, h14, made of alkali free cotton, are added with special fibers and suitable chemical additives in the production process, so that the strength and stiffness of the filter paper are greatly enhanced, with certain moisture and fire resistance. The filtration efficiency is 99.9-99.999%, In addition to being used in fields other than diaphragm high-efficiency air filter paper, the product can also meet the needs of other industries such as large air volume. It is widely used in automatic production lines of air filter paper and also suitable for small-scale manual filter manufacturing workshops. It is mainly used for air filtration in electronics, instruments and clean rooms, sterile rooms in hospital operating rooms and infection prevention wards. The filter paper can also be directly used in biochemical medicine to separate and analyze particles such as cells.We also have other filters, such as Glassfiber pocket filters and synthethic media pocket filters.If you need to contact the manufacturer.
