Mounted to the housing forwardly of and flanking the central fan are a pair of vertically rotating clearing screws. The clearing screws are mounted so as to be swingable relatively to the housing, about a vertical axis independently of each other. Each of the screws is also provided with a rear deflector plate which is also swingable about a vertical axis together with or independently of the associated clearing screw. |
