Re-assembly
The re-assembly is basically done in the reverse order than the disassembly. Wear parts, e. g.
bearings item 17 and 20, should be checked and replaced, if defective.
After re-assembly the function and performance of the pneumatic axial fan have to be checked.
For this refer to the technical specification in the assembly, operation and maintenance manual.

The minimum distance between the rotating assembly parts, e. g. the impeller, assy., item 24 and
the static assembly parts, e. g. the fan housing item 2 and 6, has to be at least 1% of the relevant
contact diameter of the complete assembly unit.
Spare Parts
Only genuine the manufacturer spare parts may be used. There is no warranty for damages and
liability is disclaimed by the manufacturer, if non-original spare parts and accessories are used.
