ABSTRACT:
A modular filter drain assembly for a duplex filter having two upright filter canisters each containing a plurality of replaceable cylindrical filter elements includes a sump base pan, liquid impervious, with sides walls embracing the lower portion of the filter canisters and of the entire drain assembly; a stand outboard of each of the filter canisters, each of the stands having vertical legs at corners, a top drain pan near an upper end of the legs and supported thereby, a filter element support pan intermediate the top drain pan and the sump pan, and a platform extending between the stands. The top drain pan has filter element receiving passages near the platform and a drain passage. The filter element support pan has a surface below the filter element receiving passages for engaging a lower edge of the filter elements and a drain passage, the filter element support pan surface being spaced below the top pan a distance sufficiently less than the height of the filter elements to cause the elements to project above the top drain pan enough to permit the filter elements easily to be removed manually from the filter element passages.
