3.1.2 Operation with lubricated compressed air
Please note
Please use non−lubricated air in your system if possible in
order to protect the environment. Festo pneumatic valves
and cylinders have been designed so that, if used as in
tended, they will not require additional lubrication and will
still achieve a long service life.
Please note the following instructions if lubricated com
pressed 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 directly in front
of the relevant cylinder.
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 DIN51524−HLP32, basic
viscosity 32cST 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 of the valves.
Setting the lubricator
With the machine running (typical operating status) 0.2 to
max. 1 drop/min. or 0.5 to 5 drops/1000 l air.
