Dust extraction
• Install flexible hoses (3) between the dust
extraction hoods (1) and the dust manifold (2).
See installation diagram with regard to the outlet
diameter of the extractor hoods. The hose length
depends on the type of hose and on the spindle
travel.
The extraction system must generate an air
velocity of 30 – 34 m/s at the outlets of the
individual extractor hoods.
Due to pressure losses and the velocity of air, the
following negative pressures must be taken into
account in the machine:
a negative pressure of 1500 Pa at 30 m/s and
a negative pressure of 2000 Pa at 34 m/s.
Hoses with flame-retardant finish must be
used for the flexible connecting leads.
Electrical connection of the dust
extractor
If continuous feed is only to run when the
extraction system is on, terminals –X20 : 30.03
and –X20 : 30.04 in the control cabinet must be
connected to a floating contact in the extractor
control. The terminal labelling must be altered
accordingly.
The electrical connections for the dust extractor
must be connected by a qualified electrician.
