Festool's CT Cyclone is an anti-static, pre-separator for large debris and coarse dust that is designed to be used with a Festool CT Dust Extractor to form a three-step filtration system. By separating large particles before it reaches the dust collector, it can reduce the overall dust load on the main dust extractor filter. The dust-heavy air that is drawn in is swirled into a spiral movement in the cyclone, causing the dust particles to hit against the wall of the cyclone and, due to the gravitational force, fall into the collection container. With tool-free assembly, the CT Cyclone includes the systainer, a systainer pan, a collection container, a hose connector, and a disposable dust liner.
