A configuration for generating blowing air or suction air, in particular a directing element in a sheet-processing machine, has a throttle path formed with vortex chambers. The vortex chambers generate vortex flows in a flow channel and they are formed by projections on just one side of the flow channel. This allows the element to be advantageously produced by molding, such as injection molding, thermo-molding, or stamping.
