Abstract
With one or several pressure streams projected at an acute angle (.alpha.) in relation to the surface to be processed, shearing forces can be reached that are high enough to move solid particles and/or fluid media and thus make it easier to suck them away. The recognition of this fact is used in a delivery/suction nozzle arrangement together with the per se known Coanda effect. The invention may be used with all fluid media, preferably for cleaning practicable and passage surfaces; also for drying and/or degassing surfaces, as well as for industrial processes, in particular substance separation processes.
