Extractor with end-mounted positive pressure system

Abstract:

An extractor system includes a negative pressure gas stream source, a negative pressure conduit, a housing, a positive pressure gas stream source, a positive pressure gas stream manifold, and an operator interface. The negative pressure conduit conveys the negative pressure gas stream from a work area. A first end of the negative pressure conduit is coupled to the negative pressure gas stream source, such that the negative pressure gas stream flows from the work area through a second end of the negative pressure conduit and toward the first end of the negative pressure conduit. The housing is disposed about the negative pressure conduit, near the second end of the negative pressure conduit comprising. The positive pressure gas stream source is coupled to the housing. The positive pressure gas stream manifold is located downstream of the positive pressure gas stream source. The positive pressure gas stream is directed through the positive pressure gas stream manifold. The operator interface allows a user to control the positive pressure gas stream through the positive pressure gas stream manifold.
