Filter discharge for very large volumes of dust.
The stationary cyclonic pre-separators are installed before the actual filter unit. They are used to pre-separate dry and granulated dusts. Medium and coarse dust particles are already filtered out in advance so that only fine dusts need to be filtered. This reduces operating costs for the entire extraction system. Cyclonic pre-separators achieve a filtration efficiency of more than 90 % with a medium grain size of at least 150 microns.
