When the really big jobs where a lot of dust is produced need to get done, your dust extractor may need to be supplemented with a pre-separator. Suction capacity greatly increases with a pre-separator attached to the dust extractor. The dust extractor's capacity to handle material that would normally be considered difficult to manage is enhanced, for example soot, burning particles, liquids and light material in large quantities. Our pre-separators are often used for renovation work, increasing capacity when grinding floors and large amounts of light material. The C-line separates 80-90% of the vacuumed material before it reaches the dust extractor. It is possible to choose between two different types of pre-separators depending on the required task: cyclone and receiver separators.
