5| Compressor assembly

5.8 Drive

The compressors of the F series can be driven by V-belts or directly by shaft couplings.
V-belt:
Proper assembly of belt drive:
- The pulleys of compressor and drive motor must be firmly mounted and in line.
- Only use V-belts with calibrated lengths.
- Select axis spacing, V-belt length and belt pre-tension according to the instructions issued by
the V-belt manufacturer. Avoid belt fluttering.
- Check belt pre-tension after running-in time.
Direct drive with shaft coupling:
Direct drive with shaft couplings demands highly precise aligning of compressor shaft and
motor shaft.

ATTENTION! Faulty alignment results in premature failure of the coupling and
bearing damage!
CAUTION! Mount suitable safeguards when driving the compressor by means
of V-belts or shaft couplings!
