The FUV pre-separator with spark arrester is a Gram Clean Air solution that protects filter units from sparks and potential fire. The unit is installed between the workstation and the filter unit, and thanks to the water bath in the base and the labyrinth structure, sparks are extinguished with water.

The FUV is especially well suited for grinding machines where there is a risk of sparks – for example when switching between grinding and polishing.
