ABSTRACT:
A device with an extraction fan for use for drawing off ambient air loaded with harmful substances during, e.g., laser surgery or HF surgery, is passed through a filter device. For routine use, easy replacement of the filter should be possible, its loading time is prolonged, and the arrangement of the filter does not compromise the easy handling of the suction line. To achieve this, a transparent sleeve 6, into which a cylindrical folded filter 10 is pulled via a perforation support tube 26, is installed in the suction line, or the filter has a hole 29 provided with a support lining, so that the filter can be directly attached to the suction-side connecting branch 5. The filter 10 is flown through radially, and thus it offers a large filter surface at minimum extension.
