be initially drained during the first phase of the recovery procedure to a level where the second opening 43 communicates with the filter chamber 30 as further shown a plurality of spin filters 26 are operatively disposed inside the filter chamber 30 for filtering the solvent based liquid of by product such as dirt grease particulates fibers and other materials that may become entrained in the solvent based liquid during the dry cleaning process 16 the plurality of spin filters 26 may be mounted on a hollow tubular member 38 which extends along the axis of the filtration tank 12 and defines a conduit 78 in communication with a third opening 45 for permitting solvent based liquid to exit the filtration tank 12 after filtration and return to the reservoir 18 in one embodiment the hollow tubular member 38 defines a plurality of openings 76 in communication with a respective spin filter 26 mounted by a collar not shown such that solvent based liquid that has been filtered by each spin filter 26 enters the conduit 78 of the tubular member 38 and exits third opening 45 for storage in the reservoir 18 as a result of this filtration procedure by product can accumulate on the spin filters 26 over time the filtration tank 12 may include a motor 34 in operative engagement with one end of the tubular member 38 through a gear assembly 46 that rotates the mounted spin filters 26 in a spinning motion when directed by microprocessor 20 this spinning motion dislodges and removes the by product that has accumulated on the spin filters 26 due to the centrifugal force generated.
