Back-pressure from
suction point
If the Multievacuator system is
installed so that back-pressure
occurs at the point of suction, con-
veying capacity will be reduced in
comparison with the figures given
in the tables on page 29.

The table below gives a correction
factor for the different Multi-
evacuator models as a function of
the back-pressure from the point of
suction.
The conveying capacity for a given
system can be calculated by mul-

tables on page 29 by a correction
factor from the table below.
Example:
If a Multievacuator 175 system
sucks a granulate with a back-
pressure of 2000 Pa, the correction
factor given in the table is 0.66.
