Cleaning system at a working table, in particular for dental technician

摘要

The workbench has a processing block (3) connected to a main suction unit (8) and a compressed air gun (4) to blast away the fine dust from the workpiece. A secondary suction device (9) is coupled to the air gun (4) and is automatically switched on when the gun is operated to draw off the dust. This secondary suction device has a funnel-shaped suction mouth piece (10) mounted on the workbench in the handling area. The suction mouth piece can be mounted at the side of the central processing block or on the workbench surface. The mouthpiece can be screened from the processing block which is connected to the main suction unit (8) so that the suction air path (7) of the main unit can be switched over to the secondary device through a swivel flap.
