Abstract

An exhaust collector for a pneumatic tool having a cylindrical body with a rotary driver at one end, an inlet port and an exhaust port for motive fluid at the other end, and a switch on the side of the cylindrical body which actuates a valve to turn the pneumatic tool on and off. The exhaust collector includes a tubular adapter on the cylindrical body defining an extension of the inlet port, a cup-shaped shroud clamped to the cylindrical body and cooperating therewith in defining a closed exhaust plenum around the tubular adapter, a first quick-connect fluid coupling on the shroud in flow communication with the tubular adapter for coupling to the inlet port a hose connected to a source of motive fluid, and a second quick-connect fluid coupling on the shroud in flow communication with the exhaust plenum for coupling to the exhaust plenum a hose connected to a remote exhaust diffuser. In a preferred embodiment, outside screw threads on the tubular adapter cooperate with inside screw threads in a bore in the cup-shaped shroud to clamp the shroud against the cylindrical body of the pneumatic tool.
