Different fibers provide each media with different dust filtration characteristics. Filter media can be further treated to improve their filtration efficiency and performance, such as lengthened filter media life cycle, better dust cake release, reduced valve pulsing, more consistent airflow, reduced differential pressure, and reduced downtime and maintenance.

Q7.How to choose material for filter bag with good price ?
Since every filter has its own characteristics and parameters, when we choose filter material for dust collector filter bag, we have to know the following parameters:
(1) Working temperature
(2) Humidity
(3) Dust diameter
(4) Gas' chemical properties
(5) Dust abrasiveness
(6) Filter's mechanical parameters
Q8.When we produce the filter bags ,you need to provide the below size :
(1)The diameter of the filter bags /the semi-perimeter of the filter bags
(2)The length of the filter bags
(3)The diameter of CPO and the thickness of CPO on dust collector on dust collector
(4)The drawing of the filter bags or the sample of the bag
(5)The material of the filter bags
(6)The type of the filter bags : round or flat ,the type of the filter bag top : snap cuff or snap ring
(7)The application of the filter bags ,cement ,asphalt ,power plant , chemical ,waste incineration , metallurgy and so on.
