Abstract: A high pressure solventless mask washer. A mask holder is slidably and rotatably mounted on a shaft within a vessel having a door through which the mask may be inserted and mounted to the holder. A rotatable output extending into the vessel is connected telescopically slides causing rotation of the holder. A spline between the holder and shaft causes vertical movement of the holder as the holder is rotated. Washing liquid is directed outwardly from the shaft against the mask with the liquid then being circulated through a filter to a main reservoir. A doctor blade removes solid materials from the filter and deposits same in a solids accumulator. A pump removes any liquid from the accumulator compartment directing the liquid back through the filter salvaging same.
