Abstract
Fumes are drawn by a vacuum source from a scoop through conduit. The conduit provides its own structure with rigid tubes and which are held with respect to one another, a mounting collar and the scoop by joint attaching assemblies and. In this way, the fume exhauster requires minimal structure. Also, joint assemblies minimize flow resistance since they are located along inside conduit curvatures.
