Abstract
An apparatus for removing dust and fumes from a flow of air, particularly a flow of air exhausted from an industrial work area. There is a large, cylindrical filter element mounted within a cylindrical collector barrel so as to define an annular flow space between the two. A vane assembly is mounted at the top of the collector barrel for directing the incoming flow of air along a generally cyclonic path through the flow space, so that sparks and heavy particulates are forced outwardly away from the surface of the filter element, thereby increasing filter life and reducing the chance of fire. The filter element and collector barrel are mounted atop a cabinet which encloses a blower and a silencer section. The silencer section includes one ore more chambers having interior walls for redirecting the flow of air exiting the blower, and the walls are lined with an acoustic insulation material for absorbing sound energy as the flow of air is redirected, thus reducing noise emissions from the assembly. The filtered airflow is exhausted from the cabinet in a vertical direction, away from the work area or areas.
