Abstract: A fluid and/or gas treatment unit containing a dynamic rotating assembly for passage of a fluid and/or gas therethrough comprises a housing having a generally cylindrical body and end walls, and a generally cylindrical member rotatable in the chamber and having a peripheral wall and end surfaces. A shaft extends coaxially through coaxial apertures in the housing end walls, and through a coaxial passage in the rotatable member with which it is engaged to rotate as a unitary assembly. Adjacent the inner surface of each end wall of the housing are, seriatim, a resiliently deflectable biasing element, a generally circular wear plate and a resiliently compressible, generally circular sealing member between the wear plate and the cylindrical member and rotatable therewith. A generally circular bearing member extends about the generally circular sealing member and the cylindrical member and is rotatable therewith.
