Thermal surface treatment

The surface of any needlefelt influences the structure of the filter cake, its cleanability as well as pressure drop and the emission.

Singed

Singed

Three different kinds of treatment are possible: 

  • smooth for adhesive and moist dust
  • medium for universal treatments
  • rough low agglomeration or fine dust
Calendering

Calendering

Through calendering a more compact fibre structure is achieved. This allows a more surface-active separation of dust with lower emission.
