There is thus virtually no risk, even when operating overhead, that liquid can enter the air outlet channel 62 and, via this, the suction unit 22.
- the separated liquid collects in the liquid tank 42. If this is to be emptied, it must for this purpose only the locking connection between the diesstechniksssammelvor- device 10 and the housing 12 by squeezing the two legs 112, 114 dissolved and the liquid collection device 16 of Housing 12 are removed.
