Abstract
A vacuum dust extraction system includes a snorkel coupled to the implement end of an air tool, a dust bellows surrounding the air tool's implement and fastened to the outboard end of the snorkel, a pneumatically powered water filtration industrial vacuum, and a suction hose coupling the snorkel to the vacuum. The apparatus features an improved coupling arrangement for attaching the snorkel to the barrel of the tool driver that permits the apparatus to work with a wide assortment of air tools.

Vacuum dust extraction apparatus for an air tool that percussively drives an implement, said air tool having a barrel, and a retainer mounted on said barrel to retain an inboard end of said implement within said barrel, said vacuum dust extraction system comprising:
- an air tool adapter mounted on said air tool, said air tool adapter having an outboard cylindrical sleeve surrounding an exposed portion of said implement;
- a tubular coupler having an inboard end removably joined to said outboard cylindrical sleeve of said air tool adapter;
- a snorkel for collecting dust produced when the implement percussively impacts a workpiece, said snorkel surrounding said implement, with a cylindrical sleeve at an inboard end thereof removably joined to an outboard end of said tubular coupler, and a sidewall in which is formed an outlet pipe;
- a bellows affixed to an outboard end of said snorkel, and surrounding said implement outboard of said snorkel;
- and
- an industrial vacuum coupled to said outlet pipe of said snorkel by a suction hose to create a vacuum that draws dust created by said implement through said bellows, snorkel and suction hose, and into said industrial vacuum.
