3.1.2 Operation with lubricated compressed air

Festo P.BE-VTSA-44-EN en 1101f
Operate system equipment with unlubricated compressed air
if possible. This is better for 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 corres-
pond in quality to unlubricated compressed air. If possible,
do not operate all of your equipment 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 (as per DIN 51524-HLP32, basic
viscosity 32 CST at 40 °C).
– The additional lubrication must not exceed 25 mg/m
(ISO 8573-1 class 5).
– Make sure that the lubricator setting is correct
(see following section)
This avoids operative malfunction of the valves.
