Why different filter bags manufacturer has different filtration efficiency?

  We take the aluminum industry for example. The smelting of metal aluminum in industry uses electrolysis. The flue gas emitted from the electrolytic cell during the electrolysis process contains a large amount of atmospheric pollutants such as sulfur dioxide, fluoride, and particulate matter. These are the most important atmospheric pollutants in electrolytic aluminum. At the same time, fluorine Chemicals can also cause great harm to the human body.

   In the actual operation of the bag filter, due to the existence of pinhole gaps at the seam of the filter bag, the dust-laden airflow will escape from these pinhole gaps. After the filter bag is cleaned, the PM2.5 emission will also increase instantly. All this makes the filter efficiency of the bag filter drop.

  However, filter bag manufacturers can also use the technology of gluing and bonding at the interface of the filter bag sewing thread to reduce the effect of sewing pinholes on the filtration efficiency. 

    Besides, if the sewing machines is good and the material is more dense, the holes will be smaller. So it's important to choose a factory with high tech production equipment.

    Contact Vision filter, all our production equipment are imported from German. We will satisfy you with quality dust collection bags.
