Flakt Vane Axial Fan failure
What Happened
What Happened
What Happened
These two fan failures were caused by human error. One was rotating backward after tripping out on a motor overload issue, not thoroughly investigated as to the cause and reset remotely at the motor control center. The rotor eventually came apart due to an internal component failure. The other fan failed due to lack of maintenance. Something internal may have come loose triggering the failure.

What Happened
What Happened
Resetting any electric equipment without first investigating is dangerous! Investigate and use a second mechanic to monitor any tripped restart. These fans are great performers and failures are rare. They do however require yearly maintenance and rebuilding when necessary.
- Only trained mechanics familiar with this type of fan should be performing maintenance or repairs.
- Only follow Factory approved procedures found in the manual, especially when locking down the blades and converting operation to a VFD from Controllable Pitch.
- Take the time to inspect ANY trip out before restarting.
