Polyester needle felt filter bag with PTFE membrane for dust collector for industrial filtration. This kind of needle felt is with good resistance to oxidation. It is widely used inmine , limestone, cement, iron and steel industries, alumina delivery, electrolytic aluminium, non-ferrous metal production industry to filter gas .
Filter bag structure should meet the requirement of filtration and dust collecting in the corresponding baghouse. at the same time, it should be easy to install, have good sealing while having relevant filtration area and condition.
The selection of filter bag matieral working conditionmust be used in the full understanding and filter under the condition of technical conditions.
* Fillter material performance should meet the production
conditions and the general situation of the dust
collectionprocessingand special requirements
* choose long service life filter materialas far as possible.Not
onlyfor saving operational costs, but alsomeet the requirements of
gas emissions standards.
* To deal with all kinds of filter material comprehensive
comparison.
