Dedusting of a secondary smelting plant in the aluminium industry
A filter medium made of meta-aramid and polyimide fibers is successfully being used in the aluminium industry.
In this special construction, the polyimide fibers are used to improve the temperature resistance and the dust collection efficiency.
The warranty term of 18 months was fulfilled and the filter bags continue to work to the satisfaction of the plant operator.
Due to our long experience in the field of industrial filtration, we will always find the best solution for every filter system.
