3.2 Compressed air preparation
Note
Unfiltered or incorrectly lubricated compressed air will reduce the service life of the
valve terminal.
3.2.1 Operation with unlubricated compressed air
Note
Too much residual oil content in the compressed air will reduce the service life of the
valve terminal.
• When using bio-oils (oils that are based on synthetic ester or native ester, e.g. rape-
seed oil methyl ester), the maximum residual oil content of 0.1 mg/m
exceeded (
• When using mineral oils (e.g. HLP oils in accordance with DIN 51524 Part 1 to 3) or
corresponding oils based on polyalphaolefin (PAO), the maximum residual oil con-
tent of 5 mg/m
This avoids malfunctions of the valves.
Excessive residual oil content is not permissible, independent of the compressor oil, as otherwise the
basic lubrication will be washed out with time.
3.2.2 Operation with lubricated compressed air
Operate your system with unlubricated compressed air, if possible. In this way, you pro-
tect 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.
Note
Operation with lubricated compressed air will cause the life-time lubrication, which is
necessary for unlubricated operation, to be "washed out".
If the system was commissioned with lubricated compressed air, a changeover to provi-
sioning with unlubricated compressed air is not possible.
Observe the subsequent information if the use of lubricated compressed air is essential:
The compressed air produced after the compressor must correspond to the quality of
unlubricated compressed air. If possible, do not operate the total system with lubricated
compressed air. If possible, always install the lubricators directly upstream of the con-
suming actuators.
