ABSTRACT:
A filter assembly is formed of an impervious elongated tubular housing and an elongated filter member positioned within the housing. In a first embodiment a barrier is interposed between a filter member first surface and the housing internal tubular surface adjacent the housing inlet end and another barrier is interposed between the filter member second surface and the housing internal tubular surface adjacent the housing outlet end. In a second embodiment, the filter member is formed of a pleated sheet, the pleats being folded at their ends, and the pleated sheet is formed into a frusto-conical shape with the conical base secured to the tubular housing interior surface. Air flowing into the housing inlet end passes through the filter member before exiting at the outlet end.
