3.1.2 Operation with lubricated compressed air
Operate your system with non−lubricated 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
service life lubrication, which is necessary for non−lubri
cated 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 non−lubricated compressed air. If
possible, do not operate the complete system with lubricated
compressed air. If possible, always install the lubricators di
rectly 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 (as per DIN 51524−HLP32, basic
viscosity 32 CST at 40 °C).
The additional lubrication must not exceed 25 mg/m
3
(ISO 8573−1 class 5).
Make sure that the lubricator setting is correct
(see following section)
You will thereby avoid functional damage to the valves.
