The article discusses the influence of design parameter of the spin flow of primary input on efficiency of dust collection and aerodynamic resistance of dust collector on the counter swirling flows. Covers theoretical and experimental dependences describing the effect of setting the initial twist of the flow on the collection efficiency and the aerodynamic resistance of dust collectors, and the optimal values of the initial intensity of the spin flow
