Replacing the filter elements:
The compressor air filter is fitted with two filter elements.
■ Primary filter element
■ Secondary filter element
The secondary filter element must be replaced at every third change of the primary filter ele‐
ment, or after two years at the latest. The secondary filter element cannot be cleaned and
reused!
The efficiency of the compressor air filter is not increased by the secondary filter element. The sec‐
ondary filter element provides an additional level of protection, in case the primary filter element is
damaged or incorrectly fitted.
