Dust collector filter bag: 
Since every filter has its own characteristics and parameters, 
when we chose filter material for dust collector filter bags, 
we have to know the following parameters: temperature, humid, 
dust diameter, gas chemictal properties, dust abrasive, filter's mechanical parameters. 
Generally, SFF dust collector filter bags are widely used in industrial waste gas filtration, useful dust, high temperature gas filters.
Shanghai filter bag factory provides you good solution according to dust characteristics, help you chose good filter material to achieve best filtering effective.
