A) Two Ø40 air channels are open
(two stop valves are open). If Ø50
is selected in the second chan-
nel, the airflow is increased as if
both channels had a Ø50 diame-
ter to maintain 20 m/s in each
channel. The display shows Ø50.

Air channel No. 1 is active (i.e. there is
airflow in the extraction tube).
The arrow indicates that the connected dust-generating
device is detected and the extraction unit is opera-
tional. Simultaneously, the stop valve has enabled the
airflow.

Channel number
It is possible to connect two workplaces. Thus, two air
channels, channel 1 and channel 2.

Measured air speed in a single tube.
Indicates the actual air speed per tube. It corresponds to
the air basis (m/s) as per configuration.

Extraction tube without airflow
In this case, the stop valve is closed (the dust-
generating equipment has not been activated).
