8.7 Fan bearing lubrication
Bearings are properly sized, with double sealed protection (2RS) and lubricated for life, therefore they do not require any
additional lubrication.

WARNING
There are a number of steps that can greatly reduce or eliminate the white rust formation on the
tightly packed components of fans delivered unassembled:
•
keep the components dry;
•
unpack the components to permit air circulation between the surfaces;
•
stack the components to allow water to drain out;
•
keep the packed components in such way to prevent moisture contact with the Munters Protect coated surface.
