ABSTRACT:
Constructions and methods are described for collecting particulate material from gas streams. In one specifically described arrangement, a region of uniform or constant density depth media is oriented upstream of a region of gradient density depth media. In another, a preferred region of gradient density depth media is constructed, to effect particulate collection in a preferred manner. Preferred constructions described herein, utilize a pleated paper filter oriented downstream of depth media, to advantage.
