What material is the fan inlet filter
The main filter requirements: It's usually fiberglass If the pressure is high, PTFE is chosen, but the price is high!
Synthetic fibre filter cotton: Under the environment of the general filter can fully replace non-woven fabric and glass fiber covered coarse, medium and high-efficient filter series products, all is the emerging of filtering material, also is the future main direction of filter material. Compared with other kinds of other filter materials, it has the advantages of small resistance, light weight, large capacity, environmental protection (incineration) and moderate price. Using (polyester fiber polyester fibre) as the main raw materials, abbreviated hereinafter referred to as: PET, polyester fiber is made of polyethylene terephthalate, also called synthetic fiber or polyester. The proportion of polyester fibers is 1.38; Melting point of 255 ~ 260 ℃, 205 ℃ when start binding, security ironing temperature is 135 ℃; Low water absorption, only 0.4%; The breaking strength of the filament is 4.5-5.5 grams per denier, and the short fiber is 3.5 ~ 5.5 grams per denier. The elongation rate of filament is 15 ~ 25%, short fiber is 25 ~ 40%. High strength fiber strength can reach 7 ~ 8 g/Dan, elongation is 7.5 ~ 12.5%. Polyester fiber has excellent wrinkle resistance, flexibility and dimensional stability, good electrical insulating properties, resistant to sunlight, rubbing, mould cavity, good chemical resistance, ability of weak acid and weak base. The trade name is: chemical fiber, chemical fiber has large chemical fiber and small chemical fiber, large chemical fiber is the polyester fiber that is made with high quality PET slice. Small chemical fiber is the fiber that some small and medium scale manufacturers use to regenerate PET slices with poor quality recycling.
Fan filter selection is mainly for your purpose and environment; The filter classification mainly has the filter level, such as the initial effect, the middle effect, the sub-high efficiency, the efficiency; According to the material, there are synthetic fiber filter, non-woven fabric filter cotton, fiberglass filter, active carbon filter etc.
