9.12 General maintenance and cleaning

Important
Remove oil residues and other deposits from unit
parts and from the coolers of compressors, which
are exposed to hot compressed air, according to
the operating instructions.
Blow off the screw compressor unit with
compressed air at the specified intervals (never
direct compressed air towards persons) paying
particular attention to:
•
Regulating elements
•
Fittings
•
Compressor block
•
Cooler
•
Electric motor
The maintenance of the electric motor is to be
performed in line with the motor operating instructions.
The electric motor is permanently lubricated.

Perform filter mat change as follows:
•
Remove mounting bolt (- 1 - Fig. 24).
•
Remove filter mat (- 1 - Fig. 24) and clean,
exchange if damaged.
•
Re-insert filter mat in the bottom access panel
(- 3 - Fig. 24).
•
Secure filter mat by means of the mounting bolt.
Cleaning:
Clean the filter mat by brushing or washing.
Important
Never install the filter mat in a wet or moist state!
Changing times for the filter mat
The operating modes and the quality of the suctioned
air (e.g. dust content) has a strong influence on the filter
service life.
The filter should be checked on a weekly basis,
eventually daily basis, for dust build-up.
In these operational cases, shorter change intervals are
possible.
9.14 Maintenance information and
lubricant recommendations for
stationary compressors
Lubricant recommendations
Please note that proper lubrication will considerably
increase the service life of your compressor unit.
According to regulations relating to the prevention of
accidents, use lubricants the properties of which meet
the requirements of the operating conditions on site.
Do not mix lubricating oils of different makes. When
changing over to a new oil type, drain the old oil
completely from the system.
If final compression temperatures of more than 90 °C/
195 °F occur continually, the oil change intervals given
in section 9.3 (maintenance schedule) are halved.
The oil change intervals should be calculated more
accurately in accordance with the actual operating
conditions by analyzing the oil.
Use the following oil type:
