The adjustment value for the sealing air depends on the hose diameter and
length.
Ü
Hose diameter: DN 2.8
Ü
Ensure that the following values are observed at the sealing air connection
of the HF spindle.
Air pressure Min. 1 bar
Volumetric flow Min. 20 Nl/min
Ü
Make sure to observe the loss of pressure that arises due to the hose used.
Ü Bear this loss of pressure in mind for the adjustment values on the ma-
chine.
Ü To ensure effective control, turn on the sealing air and cooling when turn-
ing on the machine. This protects the HF spindle even when it is stationary.
