An apparatus for adsorptive filtering of contaminants from a gaseous stream is provided. The apparatus includes a frame member. The frame includes a base member which is rotatable about an axis. A plurality of walls are attached to the base member and extend axially therefrom to a top member for providing a plurality of circumferential segment areas. The walls include a radially inner side for defining an axially extending inner chamber and a radially outer side for defining an outer periphery. A plurality of adsorption elements, each having an axial first side and an axial second side, are axially spaced in each of said circumferential segment areas. A duct or the like radially directs contaminated air into at least an entire one of the segment areas. The apparatus has a duct arrangement for directing a substantially radial flow of air into at least one of said segments from the outer periphery through the axial first side of each of said adsorption elements in generally an axial direction through the adsorption element to exit the axial second side and into said axially extending inner chamber for exhausting decontaminated air out through the axial chamber. The present invention may also include a regenerative portion which can regenerate the adsorptive elements during operation of the apparatus. The regenerative portion includes ducts for supplying a heated regenerative air stream and a cooling air stream to strip contaminants from the adsorptive elements and then cool them to a suitable adsorptive temperature.
