ABSTRACT:
A centrifugal filter device includes a housing having an essentially cylindrical housing wall about an axis of the housing and an annular trough located radially inwardly of the housing wall, a cap fitted to the housing and having a lid spaced from an upper edge of the housing wall, the cap further comprising an annular side wall spaced radially outwardly from the housing wall and defining an annular catchment chamber having an annular tapered deflection surface therein, a first exit port in the side wall of the cap, a second exit port at the trough of the housing, an inner chamber situated within the housing and adapted to rotate about the axis, the inner chamber having an essentially cylindrical wall inwardly spaced from the cylindrical wall of the housing so as to define an annular space therebetween, an internal drain communicating an interior of the chamber with the trough of the housing, and an annular closure element having an opening communicating the interior of the chamber with the annular catchment chamber of the cap, and an inlet extending from outside the filter through the cap and the opening of the closure element to the interior of the chamber.
