3.1.2 Operation with lubricated compressed air

Festo P.BE-CDVI-EN en 1202e
Operate your system with unlubricated compressed air if
possible. This will prevent pollution of the environment.
Festo pneumatic valves and actuators have been designed
so that, if used as intended, they will not require additional
lubrication and will still achieve a long service life.
Caution
Operation with lubricated compressed air will cause the
life-time lubrication, which is necessary for unlubricated
operation, to be "washed out".
Note the following instructions if lubricated compressed air
must be used.
The compressed air prepared with the compressor must
correspond in quality to unlubricated compressed air. If poss-
ible, do not operate the complete system with lubricated com-
pressed air. If possible, always install the lubricators directly in
front of the consuming actuator.
Caution
Incorrect additional oil and too much residual oil content in
the compressed air will reduce the service life of the valve
terminal.
– Use Festo special oil OFSW-32 or the other oils listed in
the Festo catalogue (conforming to DIN 51524-HLP32,
basic viscosity 32 CST at 40 °C).
– The additional lubrication must not exceed 25 mg/m
(ISO 8573-1 class 5).
– Check that the lubricator setting is correct (see sub-
sequent section)
This avoids operative malfunction of the valves.
