Abstract
An improved filter system is disclosed for filtering a liquid media such as molten metal, e.g., molten aluminum and aluminum base alloys, the system comprises a housing containing a first chamber into which molten metal to be filtered passes, a second chamber in the housing, a filter cloth that separates the first chamber from the second chamber, a high specific flow static filter in the second chamber, and means for moving the filter cloth in the housing to expose fresh surfaces of filter cloth to the metal being filtered to inhibit clogging of the filter cloth means by buildup of the filter cake and maintaining a constant high level of filtration efficiency.
