Schumalith® Filter Elements

Pall Schumalith filter elements are manufactured from a porous, ceramically bonded silicon carbide filter media that has a high mechanical strength.

This ceramic filter material is distinguished by its excellent thermal resistance as well as thermal shock resistance. For this reason Schumalith filter elements are well suited for the filtration of hot fluids with fast temperature changes. The high performing Schumalith filter elements are mainly used for high temperature applications.


General Information

  • Machining is possible using diamond tools.
  • Elements can be glued using commerical or special ceramic glues.
  • Careful consideration should be taken regarding operating temperature and chemical resistance.

• Particle filtration of gases Gas analysing, devices, filtration of hot gases
• Coalescer Coalescer for oil aerosols in hot gases

Performance

Chemical Resistance4

Schumalith filter elements are resistant against acids, saline solutions and organic solvents, liquid or gaseous. They are not resistant to hydrofluoric acid. Schumalith filter elements are resistant up to pH 10 in the alkaline range.


4As end use conditions can vary, it is the users responsibility to verify compatibility with their specific use conditions.
