Copes with high volumes of dust. Efficient, simple, and reliable. High volumes of dust, shavings, and chips are no longer a problem for neither the main filter nor for the suction power. The pre-separator (compatible with CT mobile dust extractors) collects up to 95% of dust before it reaches the mobile dust extractor. This reduces the load on the main filter and ensures consistently high suction power throughout the work process. Main applications: Extraction of large volumes of fine mineral dust Extraction of large volumes of chips from sawing, planing and routing For all applications with diamond grinders, long-reach sanders and renovation millers with large quantities of fine dust For all applications with saws, routers and planers with large quantities of coarse chips Quick and easy disposal of large dust volumes
