ABSTRACT:
A new accessory for duct systems for displaying the degree dustiness in a duct network and for trapping heavy and potentially valuable objects as they are cleaned from a duct network. The inventive device includes a housing that has an exterior wall and an open top. The exterior wall has an interior surface that defines an interior of the housing. The open top provides an opening into the interior of the housing. A filter sheet is disposed in the interior of the housing. The filter sheet has a plurality of apertures therethrough. The filter sheet divides the interior of the housing into a first chamber and a second chamber. The exterior wall of the housing has an aperture into the first chamber and an aperture into the second chamber. A cover is dimensioned for coupling with the open top of the housing. The cover closes the opening into the interior of the housing.
