29
YES NO
The FilterMax DX pressure
resistance is high.
D
Are there some valves that are
functioning?

B
NO YES
Check the pressure of the com-
pressed air. It should be 0,6 MPa
(6 bar, 87 psi).
Is the cleaning system fully
functioning?
Check the pause time set on the
timer (see page 16). The default
value is 30 s. A heavy application
or a 2 - 3 module unit (12 - 18 filter
cartridges) will require shorter
times. A very light application can
use longer times.
If the cleaning has been adjusted
previously you may have to replace
the filter cartridges.
NO
YES
Check if the system contains any
dampers and the position of these.
Open dampers to adjust the flow,
but don’t exceed the dimensioned
airflow for the filter unit.
Check that the filter unit’s inspection
panels are closed.
Check the fan for blocked outlet or
other damage.
Open the filter unit’s inlet inspection
door on the top of the inlet and
check for blockage, clean if
necessary.
If the inlet is blocked/partly blocked
by sticky dust/particles open the
inspection panel on the top of the
unit and clean the preseparator.
NO YES
Is the fan operating correctly?
Does the impeller rotate in the
right direction?
Contact your nearest Nederman
representative for advice.
Check the rotating direction of
the fan impeller. Compare with
the arrow on the label on the fan
motor. It is very important that
the rotation direction is right.
If the impeller rotates in the wrong
direction, the fan gives only 40 %
of its possible air volume. Contact
a qualified electrician if the im-
peller rotation must be reversed.
Has the airflow been satisfactory?
NO
The airflow is insufficient.

Is the pressure resistance high
( >1000-1500 Pa)?
