Pyropore Ceramic Foam Filters


Pyropore ceramic foam filters (CFFs) are high-quality filters used in molten aluminium, copper-based alloys and ferrous metals including grey, ductile and steel alloys. Pyropore CFFs are efficiently remove oxides and non-metallic particles. 

Pyrotek Offerings

Pyrotek's Pyropore ceramic foam filters are proven, high-quality filters which provide ultimate molten aluminium filtration. Constructed of high-strength ceramics, Pyropore provides a superior metal filtration. Ceramic foam filters are easily installed and provide an excellent solution for the removal of oxides. 

There are four different types of Pyropore ceramic foam filters:

  • Partially stabilized zirconia (ZrO2) ceramic filters
  • Silicon carbide (SiC) filters
