Drache’s Ceralu filters are manufactured in porosities from 10 to 70 PPI. Many industry standard sizes are available and custom-made cut-to-size filters are also possible.

The filters are placed in the melt usually inside a filter box. Complete metal filtration units with gas or electric filter tile pre-heat system are also available.
