Abstract
A multiple cartridge filter assembly is provided with a removable filter array to facilitate the rapid replacement of an entire array having spent cartridges with another identical array having fresh cartridges, after which the spent cartridges of the removed array may be replaced. The removable filter array includes a separation plate from which the filter cartridges hang suspended in sealing engagement therewith and a dual position support platform connected to the separation plate and located beneath the lower blind ends of the cartridges. The support platform maintains the cartridges sealingly engaged with the separation plate when the removable array is in its working condition but automatically drops down relative to the separation plate when the array is removed to accommodate the replacement of the cartridges. In the preferred practice of the invention the movement of the support platform relative to the separation plate is limited to that which permits removal of the filter cartridges at an angle but not vertically.
