12.1 Troubleshooting

Table 5 Troubleshooting

Problem

Possible causes

Remedy

Fan does not run
smoothly

Impeller imbalance

Rebalancing by a specialist company if possible,
otherwise contact Systemair.

Soiling on the impeller

Clean carefully, rebalance

Material decomposition on the
impeller due to aggressive
material conveyed.

Contact Systemair

Impeller rotates in wrong
direction.

Change direction of rotation if possible, otherwise contact
Systemair.

Deformation of impeller due to
excessive temperature.

Ensure that the temperature does not exceed the certified
value/Install new impeller.

Vibrations, oscillations

Check the installation of the fan/check the duct system,
see 8

Installation

, page 7.

Fan operation in resonant
frequency range

Consider chapter 9.2

Variable-speed fans

, page 9

Air output of fan too
low

Impeller rotates in wrong
direction.

Change direction of rotation if possible, otherwise contact
Systemair.

Wrong wiring configuration (e.g.
Y instead of Delta).

Check and possibly correct the wiring configuration.

Pressure losses too high.

Optimize the line routing.

Flow regulators not or only
partly open.

Check opening position on site.

Intake or pressure ducts are
blocked.

Remove the blockage.
