Abstract: A rapid-flow washer for photographic sheet material, such as prints or films, in the form of a tank having a fluid inlet near the bottom including an aerator for introducing a mixture of air bubbles and water into a horizontal distribution manifold at the bottom of the tank, the top of said manifold being a horizontal septum perforated with small perforations, and having also parallel rows of larger perforations for receiving the ends of removable wire sheet separators to thus form parallel rows of such separators spaced far enough apart in the rows to permit manual insertion and removal of single sheets. A vertical septum near one end of the washer provides an overflow compartment at the bottom of which is an outlet nozzle.
