Fault description Cause Remedy Personnel
Air volume flow rate
is incorrect
Open the bypass
Reduce pressure losses in the duct
Dampers or grilles in
the system are closed
Open the dampers or grilles Instructed person
An object is obstructing
the airflow in the duct
Clean the duct / remove the obstruction Instructed person
Vane controls are (parti-
ally) closed
Open the vane control Instructed person
Filter is dirty Clean or replace the filter Instructed person
Fan is pumping Fan is working in an
unfavourable character-
istic curve range
Reduce the system resistances. Instructed person
Increased vibrations Impeller imbalance due
to deposits
Please note that the system, consisting of the
impeller and motor, always has a residual
imbalance, even if all of the components are
balanced!
Clean and rebalance the impeller
Instructed person
Vibration isolators are
assembled or posi-
tioned incorrectly
Incorrectly selected vibration isolators can
result in the destruction of the fan!
Construct and assemble vibration isolators
correctly
Instructed person

the wrong size
Replace the vibration isolators Instructed person
Air noises Direction of rotation is
incorrect
Change the direction of rotation by switching
two live wires on the terminals
Skilled qualified

passage of air
Install baffle plates
Instructed person
Is the operating point in an unstable range?
Implement measures to reduce the overall
pressure loss
Instructed person
Mechanical noises Contamination on the
casing or impeller
Clean the casing / impeller Instructed person
Impeller is grinding Caused by a misaligned connection duct due
to deformation of the casing, for example.
Check the impeller gap
Realign the fan
