Latest Products In Market China Filtrates Use Filter Media Manufacturers 

Air filter non woven is made of PET fiber and can be divided into non-glue non woven and glue-spray non woven according to the process.. The non-glue non woven is baked based on the combination of ordinary PET fiber and ES fiber(low melting point polyester fibre), and it may use fiber of different degree of thickness to make the filter non woven of thickness of 5-30mm to guarantee different filtration effects. The air filter non woven filtration can be divided into G1, G2, G3, G4 and F5 according to European filtration classification and preliminary-efficiency, medium-efficiency and medium-high efficiency filtration according to China’s filtration classification, which is commonly used in panel air filter and pleating panel filter. The main characteristics is large air flow, small resistance, solid structure and can be repeatedly cleaned.

The glue-spray air filter non woven is made based on glue spray after webbing of  PET fiber and non woven can be made in a thickness of 5-30mm. The filtration can be divided into G1, G2, G3, G4 and F5 according to European filtration classification and preliminary-efficiency, medium-efficiency and medium-high efficiency filtration according

Primary effect filter cotton (non woven fabric) also is called  early effect filter cotton, used in various industrial applications: such as coating industry, electroplating industry, surface treatment, waste gas treatment, building ventilation, pollution prevention, public construction, air-conditioning industry, household electrical appliance industry, automobile industry, motorcycle manufacturing, electronics, clocks and watches industry, pharmaceutical factory, food industry, packaging materials, furniture industry, decoration engineering, ventilation, air adjusting system each air purification field. Filtration efficiency for 5 m particles were 40%, 65%, 80%, 90%, European Standard Specification for G1, G2, G3, G4, EUROVENT4/5 level: eu1 and Eu2, Eu3, EU4 a geotextile filter or volume, to send the outlet size cut, mounted directly to the outlet, windward regular white, add color, green, blue, yellow, and so on; and waterproof processing, with cleaning function. On the network, with the single cabbage paper tube can be used for automatic roll filter unit.

Service life                                                                                      
In rated air flow conditions of use, can be used normally 1 ~ 2 months, that is required to replace the filter cotton; or when the resistance of the filter cotton reached more than 200Pa, must replace the filter cotton, filter cotton is washable, replace the filter can with water or with neutral detergent solution washing, dry with compressed air or cold dry, then put on; allows up to secondary cleaning, that must be replaced with a new filter cotton, and each cleaning, filtration efficiency will reduce 15%; such as the use of environment in the dust concentration is very high, the use life cycle will also reduce containing.

Fire retardant curtain fabric to China’s filtration classification to meet burning class S4, smoke class SR2, dripping class ST2, which is widely used in panel air filter and pleating panel filter; it also can be used for the air cleaner of the metro ventilation,train’s air conditioner and other public facilities filtration. Glue-spray cotton has solid structure, large blast capacity and small resistance, and it can be repeatedly cleand.
