  • Patent number: 8726774
    Abstract: A downdraft enclosure and curved shroud forming a 180 degree catch area for dust and debris created by miter saw operation in at any angle or position. The enclosure defines a downdraft space. Exhaust opening perforations are formed on the top of the enclosure, with a dust outlet opening formed in the base of the enclosure. A flexible hose from the saw housing to the downdraft space captures debris ejected in an upward direction; the shroud, top of the enclosure, and miter saw fence capture dust ejected in outward, side and downward directions. A hose may be installed on the dust outlet to continuously carry the debris directly to a vacuum, thereby continuously keeping a workspace clear of debris ejected in all directions regardless of the saw's cut angle or position.
