Reading the minimum volumetric
flow
A pressure gauge showing the vacuum in-
side the device is mounted on the front of
the device. The main filter must be cleaned
when the maximum vacuum (see table) is
reached (see chapter
Dedusting the main
filter ). This value depends on the device
performance and the suction hose used. If
the vacuum is not significantly reduced by
dedusting, the filter must be replaced (see
chapter
Replacing the main filter ).
ATTENTION
Exceeding the maximum vacuum
Suction loss
If the specified value is exceeded, the air
speed in the suction hose drops below
20 m/s. Clean or replace the filter.
Dedusting the main filter
The main filter must be cleaned if the pres-
sure gauge shows the maximum vacuum
(see chapter
Reading the minimum volu-
metric flow ).
