ApplicationInstead of high temperature filter bag dust removal, High temperature condition
※This series uses aramid and polyphenylene sulfide needle felt (PPS) as the substrate, treated with high-temperature stiff coating and PTFE membrane.
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.
