Primary filter cotton, available in thin and thick sizes. The thin one is 1-8mm of the acupuncture process, and the thick one is 0.5-8cm of the hot air process. It is economical and practical, with low initial resistance, high dust capacity, elasticity, safety and environmental protection, and easy to use. This series of products is mainly used for the pre filtration of the purification system, which is commonly used in the air purification filtration. Common filter materials are used to filter ≥ 5 in the atmosphere μ Mainly composed of particulate dust and suspended solids.

　　Product characteristics

　　Suitable for areas where filters need to be cleaned frequently, such as pre filtration in air filtration systems. The main components are mostly PET (polyester fiber) and PP (polypropylene fiber), and the usual production process methods generally use hot air method and needle punching method.

　　service life

　　Under rated air volume usage conditions, it can be used normally for 1-2 months, requiring replacement of filter cotton; Or when the resistance of the filter cotton reaches above 200Pa, the filter cotton must be replaced; If the filter cotton is washable, the replaced filter material can be washed with clean water or a solution containing neutral detergent, dried with compressed air or cooled, and then replaced; It is allowed to clean twice, that is, it is necessary to replace the filter cotton with a new one, and each cleaning will reduce the filtration efficiency by 15%; If the dust concentration in the usage environment is high, the service life cycle will also be reduced.

　　Scope of use

　　Used for various industrial purposes: such as spraying industry, electroplating industry, surface treatment, exhaust gas treatment, building ventilation, pollution prevention, public construction, air conditioning industry, home appliance industry, automotive industry, motorcycle manufacturing, electronics industry, watch industry, pharmaceutical factory, food industry, packaging materials, furniture industry, decoration engineering, and other ventilation air conditioning systems in various air purification fields.
