There is provided an exhaust extractor (10) for coupling with an exhaust pipe of an internal combustion engine (13, 14) in order to convey the exhaust gases to a safe discharge point. The extractor comprises a wheel-supported frame (16, 17) to render the extractor mobile, and an extractor fan unit (18) is mounted on the frame having an electric motor coupled with a suction fan, in which the unit is sealed to meet flameproof requirements for the particular operating environment. An intake fitting (19) is mounted on the frame (16) and takes the form of a slide plate (26) slidably mounted on the frame and having one or more inlet fittings (27) for receiving the ends of one or more flexible inlet pipes (15) coupled with respective exhaust pipes, and a gas output fitting (22) of the extractor (10) is coupled with an output of the suction fan and adapted to receive one end of a flexible outlet pipe for discharging the extracted gases to a safe discharge position. |
