perma Lubrication Systems for
Blowers / Fans

Blowers and fans are used in almost all key industries where  Mining
they provide adequate amounts of primary and secondary air.  Chemical industry
Flue gas fans remove air containing dust, gases and other  Glas industry
harmful substances.  Wood-working
In primary air zones, induced draft fans are used in scrubbers,  Power plants
dust collectors, heat exchangers and desulfurization plants.  Food industry
 Refinery

Lubrication points

The lubrication points (roller bearings) are located at the drive shaft
Drive shaft between drive motor and fan impeller.
bearing and Drive motor
seal
Bearings and shaft seals must be permanently supplied with the right
lubricant in the amount specified by fan manufacturers.

Challenges

Blowers and fans are often used in extreme operating conditions with many
contaminants in the air. Dust and other substances entering the bearing system
will lead to increased wear of individual components and a shorter service life
of the fan.

 Contaminants (e.g. dust) in the air must not enter lubrication points

Regular lubrication of bearings and seals is essential for uninterrupted
operation. Fan and blower lubrication points are often extremely dirty and hard
to reach, which makes maintenance even more difficult. When manufacturer
recommended lubrication intervals are not observed, the system will eventually
fail as a result of lubricant starvation.

 Excessive bearing heating from insufficient lubrication
 Lubricant must meet operating requirements (vibration/ oscillation,
speed, operating temperature, load)
 Observing re-lubrication intervals (depending on bearing type, bearing
size and ambient conditions)
