Filter Tubes, Filter Cylinder

The unique porous structure of VitraPOR® sintered glassfilters makes it flexible and incredibly versatile not only for established uses but also for many other applications.

VitraPOR® glass filters are divided into porosity classes ranging from 1,0 µm to 500 µm.

Filter Tubes, Filter Cylinder
Cylindrical filter tubes are produced in our modern tube furnace.

More than 1.000 degrees Celsius are necessary for over 12 hours time to sinter tubes with diameters up to 150 mm and 400 mm length. Computerised temperature controllers allow exact timing of the heating, sintering and annealing phases.
