5 Maintenance
Wearing parts are subject to the recommended maintenance
intervals and are a constituent part of the applicable warranty
claims. The service life of wearing parts (ball bearings and filters)
depends on the operating hours, the load and other influences,
such as temperature, etc.

5.1 Ball Bearings

The fan is equipped with enclosed deep groove ball bearings,
which do not have be to re-greased and have a minimum service
life of approx. 12,000 hours. We recommend exchanging the
ball bearings before the end of service life (at least 12,000 hours).
The 18-month operating time is not to be exceeded given con-
tinuous operations of 24 hours a day.
