4.5 Dust Extractors
The machine has to be connected to a dust extractor. The
connection values and the position of the connection port
are shown on the picture.
The air speed at the connection point has to be a mini-
mum of 20 m/s for materials with a humidity less than
12 %.
The air speed should be increased to 25–28 m/s to ex-
tract dust from more humid materials (over 12 %).
Only flame resistant vacuum hoses can be used, conform-
ing to DIN 4102 B1 and any other safety regulations in
effect.
