Abstract: An enclosure or housing for removal of sawdust generated by a saw blade rotating on a shaft located below a work table. A portion of the rotating saw blade projects above the top surface of the work table to engage and saw material being moved on the work table. The saw portion below the work table is located in the chamber formed by the enclosure and the chamber is connected with a source of suction. The enclosure straddles the saw rotor shaft, and its side walls have U-shaped upwardly opening slots through which the rotor shaft extends, located at each side of the saw blade. The slots and one side wall top edge have air seals between the saw blade and said slots and top edge. The saw blade is located parallel with and close to the unsealed enclosure side wall and is spaced a greater distance from the opposite sealed side wall. A top guard having a cover chamber may enclose the portion of the saw blade projecting above the work table. When used, the cover chamber also is connected with the source of suction.
