The air velocity must be checked before initial commissioning
and after significant changes. The extraction system must be
checked daily for obvious defects after initial commissioning
and monthly for effectiveness.
The machine must be connected to an effective extraction
system on-site. The upper extraction nozzle on the extraction
hood has a diameter of 80 mm. The diameter of the lower ex-
traction nozzle on the machine stand is 120 mm.
Two signal transmitter lines for automatic switching of the
extraction unit can be connected to the terminals “03” and
“04” of the contactor “K2”.
Installation only by a qualified electrician!
The air speed must be set in such a way that, with the extrac-
tion line connected and the tools stationary, an average air
speed of
When the machine is switched on, the extrac-
tion system must start automatically.
- 20 m/s (1450 m³/h) with dry chips,
- 28 m/s (2050 m³/h) with moist chips (moisture 18 % or more)
is achieved at the extraction nozzles.
Existing negative pressure at 20 m/s: Total connection 140 mm Ø / approx. 1200 Pa
