The cyclone consists of a conical part and a spiral outlet, in which a rotating air (gas) flow is formed, and due to inertia (centrifugal force), dust particles are removed through the outlet. The air (gas) stream cleaned from dust is removed from the cyclone through the coaxial exhaust pipe.
- They are made of left and right versions (the right one is the rotation of the gas flow clockwise, when viewed from the side of the exhaust pipe, left counterclockwise);
- They are conical cyclones;
- Unlike cylindrical ones, they have large overall dimensions (therefore, they are not used in group execution);
- Due to the elongated conical part, they provide the highest dust collection efficiency.
