A centrifugal filter apparatus including a canister housing having a frusto-conical internal surface, and outlet adjacent the minor diameter of the internal surface and an inlet spaced axially toward a major diameter, a central annular filter element and centrifugal radial rotating fins extending radially from adjacent the external surface of the filter element to adjacent the generally frusto-conical internal surface of the canister having a generally frusto-conical outer surface conforming to the frusto-conical internal surface of the canister. In one embodiment, the filter apparatus includes a plurality of reaction canisters, where the outlet of the first canister is the inlet of the second canister and the radial fins drive reaction products from the first canister to the second canister.
