Classification of filter cotton
According to the national standard (GB/T14295), filter cotton can be divided into: rough (primary) effect, medium effect, high efficiency, according to the European standard can be divided into: G1,G2,G3,G4,F5,F6,F7,F8.
Coarse (primary) filter cotton (tuyere cotton) mainly filters dust particles larger than 5 microns, which is generally used for ventilation equipment and air control system suction inlet as pre-filtration or coarse filtration and other direct contact with outdoor air.
Also used for plate filter, folding plate filter, bag filter and other filter equipment filter material.It can also be used for pre-filtration under high dust exposure in the air supply system.Prefiltration of air supply and filter material with uniform flow in spraying system and baking equipment。
Medium filter cotton (canopy cotton) mainly filters dust particles larger than 1 muon, generally used for secondary or final filtration after coarse filter, but also for plate filter material.
High-efficiency filter cotton: it is mainly used in hospitals or laboratories where filtration requirements are especially high.
FSC company is a professional production of filter cotton company, in the production, research and development, application has a leading position.The filter cotton produced by the company includes PET filter cotton, color filter cotton and primary filter cotton.
PET filter cotton: PET fiber with different diameter of silk is processed by non-spinning process. Hollow 3D fiber ensures the product is light and elastic.The colors are white, black, gray, blue, green;The filtration levels are G2, G3, G4, M5, M6 and M7.
Color filter cotton: PP/PET/PES polyester fiber, PP fiber processing.Applied to the ventilation system at the beginning/middle effect filtration, machine inlet filtration, exhaust system exhaust gas filtration, liquid filtration, sewage treatment;Color customized.
