Filter cloths

The right choice of filter element is important for the efficiency of filtration. The raw materials differ mainly in terms of their resistance to chemicals, temperature and mechanical stress.
We must consider not only permeability, but also type of fiber, yarn, weave pattern and finishing treatments of the material.

But always to remember: it is the quality of processing and therefore the quality of obtained crystals, that make our filtration easy, or difficult.
