Industrial Fan Repair

Industrial Fan Repair

Industrial fan repair is a specialty of Prime Machine.  Whether it is on-site vibration analysis, replacing bearing, laser alignments of motor to fan, dynamic balancing or a complete shop rebuild of rotor we have the expertise.

We have saved our customers substantial money and time by field machining new bearing fit on site at their plant saving the dis-assembly, shipping, shop work and reassembly of large fans.

In our shop we have all the fabrication and machining capabilities to complete extensive industrial fan repair.  Complete manufacture of new shafts in our large lathes.  Complete detailed reverse engineering of all features and materials so that rotors are exact duplicates.  Shroud metal spinning, complex fabrication of wheels with machining of new wheels hubs to fit shaft.

The installation of shaft in the new wheel.  Dynamic balance of fan rotor in the shop.

Additionally should grouting of soul plates be required we are capable of placing the new soul plates and grouting them in position.
