Applications

Smelting and roasting furnaces, drying drums, reactors, furnaces, etc.


Advantages

  • high cleaning efficiency   
  • low aerodynamic resistance   
  • chemical resistance: to acids (except hydrofluoric acid), salt solutions and organic solvents.
Working principle 

Granular ceramic filter elements are made of coarse-grained silicon carbide or aluminium oxide (substrate) with a thin selective layer - membrane - applied on the outer surface. The pore size of the substrate and membrane is selected based on the specific task, based on the data on the disperse composition of the separated particles, the required aerodynamic resistance and the efficiency of gas purification.
