Onsite balancing of a ventilator

Determination:

Excessive vibration levels were measured near the fan bearings.

Proposition:

The cause of the elevation can be attributed to the imbalance of the fan. Due to time constraints, it was impossible to dismantle the fan and the decision was made on the spot to balance it.

Decision:

The standstill was limited to a minimum because we were able to solve the imbalance problem of the ventilators without dismantling the ventilator.
