7.3 Hydraulic installations
PVC-U pipes or PE hoses are used as conduits. If the line is to supply
multiple consumers, the line should be calculated for the total of the
consumption volume.
The following nominal widths are recommended for the vacuum line
(pressure loss max. 25 bar, calculated at 0.9 bar (a) with 4x90° angles):

Where necessary, a large distance can be installed in a large nominal
width and a connection in the nominal width of the device can be selected
for shorter sections shortly before and after the device.
