For use with all Festool CT 26/36/48 Dust Extractors, the CT Cyclone is an anti-static, pre-separator for large debris and coarse dust. Reducing the overall dust load on the main dust extractor filter, the pre-separator draws dust-heavy air in, swirls it into a spiral movement in the cyclone, and causing dust particles to hit against the wall and fall into the collection container. The stackable collection container can be attached and removed tool-free. When used together, the CT Cyclone and CT Dust Extractor provide a three-step filtration system and reduce the number of filter bags needed.
