Solution Agitation by Means of Compressed Air

Agitation of the developing bath by means of compressed air or other gas is most effective when the upward stream of air bubbles is made to follow the surface of the film. When the air is released at the bottom of the tank, the induced stream usually passes up through one portion of the tank without reaching all parts of the film. The stream can be made to follow the surface of the film in a vertical rack type developing machine by the use of an air distributing gridwork which discharges the air at a large number of points distributed along the film strands from bottom to top of the rack.
