aramid needle punched felt are made from the aramid yarn, after needle punched we can get the common 450gsm, 500gsm, 550gsm aramid filter cloth.
There are two kinds of aramid filter cloth used in dust filtration:
1.aramid fiber with aramid scrim
2.Aramid fiber with fiberglass scrim
The aramid filter media common treatment:
Singed, calendered, heat set or water&oil repellent, anti-static, PTFE membrane/coating
The diameter of the filter bag is: diameter 100mm, 125mm, 130mm, 150mm, 180mm, 250mm etc.
Any length is available. Special size is customize.
The aramid bag filter process Method: sewing or welded
High temperature resistant
Working temperature: 204 degree
Max temperature: 240 degree
Excellent alkali resistance
Good acid resistance
Good organic solvents resistance
Excellent abrasion resistance
Good hydrolysis stability
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 chemical 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
