Step 6
Recalculation of the volume flow per vacuuming point.
Example:
With a pressure loss performance of 79 mbar, a volume
flow of ~420 m³/h remains with IV 100/75.
Volume flow per vacuuming point:
420m³/h / 2 vacuuming points = 210 m³/h per vacuuming
point.
Step 7
Calculation of the actual flow velocities in the sections and
subsequent alignment with the necessary air speed of the
application:
Example:
With the IV 100/75 the required air speed can be reached
in all sections.
