Vacuum connector
Diameter
120 mm
Volume flow
814 m³/h (at 20 m/s)
Vacuum
917 Pa
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.

Specifications
Warning! Risk of injury! The dust extraction hose must be non-flammable and must not conduct electricity! For
this reason, only use genuine FELDER dust extraction hoses!
Note: As a rule, all units must be vacuumed during use. A time delayed socket is available as an accesso-
ry.
• In addition, the vacuum performance must be sufficient
to achieve the required negative pressures and an air
speed of 20 m/s at the connector. (see “Technical
data”)
• Check the air speed before putting the machine into
operation for the first time and after essential changes.
• The dust extractor setup must be controlled before the
machine is put into operation for the first time. Check for
obvious defects on a daily basis and the efficiency on a
monthly basis.
• The dust extractor must be connected to the machine
in such a manner that it runs in unison with the
machine.
• The dust extraction hoses must be electrically conduc-
tive and grounded to prevent electrostatic
build up.
• Use dust extractors with reduced dust emission to clean
dust from the machine.
