A device comprising a flow celldefining a treatment region thatcontains a treatment location thatextends along a plane for thechemical or electrolytic surfacetreatment of plate-shaped articlesat the treatment location, when amain plane of the articles extendsalong the plane along which thetreatment location extends, withfirst feed elements in the form oftubes with outlet openings for thedirected supply of a process liquidto the treatment region, charac•terized by additional, second feedmeans in the treatment region forthe directed introduction of airinto the active area of guide ele•ments, which consist of flow grat•ings maintained at a distance on
both sides of the treatment loca•tion, with small plates arrangedin the manner of a shutter, whichare inclined upward and down•ward in the direction parallelwith the plan along which thetreatment location extends.
