This series are surface treated media which has characteristics of extremely high filtration precision, long service life, good permeability, easier dusts cleaning, etc. It can add various functional treatments according actual application conditions. It is mainly used for all kinds of toxic and harmful ultra-fine dust and flue gas treatment, but it should be used with caution in oily smoke. Suitable for the filtration of very fine dust type in welding fumes, mechanical processing, pharmaceutical and construction industries and sticky dust collection. 


Remark:
a. Air Permeability was tested at △P=200Pa.
b. Filtration Precision, this data refers to the minimum grade of particle size that can be effectively blocked before the initial "dust-cake" is established. In the practical using processes, we can improve the filtration precision by using correct filtration velocity, and establishing stable initial "dust-cake", etc.
c. Filtration Efficiency was tested by using 8-12 micron 325 mesh talcum powder as test dust with the filtration speed ≤ 1.2m/ min and the concentration of dust (4±0.5) g/m3 ; after more than 5 times cleaning process, filter media makes a good effect on the ratio of filter effectively blocking dust and the total quantity of dust. (JB/T 10341-2014)
d. Filtration Precision Level is tested at the beginning of using, by ASHARE52.2 in USA or EN779 in Europe.
★The various functions of the filter media can be combined with each other, please contact us with your special needs.
★All technical parameters are for reference only (test data may deviate due to test different conditions and equipment), we reserve the right of making changes without prior notice.
