Filter papers for technical applications
Smooth and thick filter papers
The filter papers listed below are mainly recommended for technical applications such as industrial filtrations. They are available
as sheets, filter circles, folded filters (in part), cuts of almost any shape and as rolls. On request, we will be glad to produce other
filter papers or filter papers with special properties as to customers demand.
