    (see ISO 8573-1 class 4). You will thereby avoid functional damage to the valves. Excessive residual oil cannot be permitted irrespective of the compressor oil, as otherwise the basic lubrication will be washed out during the course of time. Festo P.BE-MIDI/MAXI-03-EN en 0209f...

  • Page 37: Operation With Lubricated Compressed Air

    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 vis- cosity 32cST at 40 °C).
  • Page 38 A further indication of excessive lubrication is the col- ouring or status of the exhaust silencer. A distinctly yellow colouring of the filter element or drops of oil on the silencer indicate that the lubricator setting is too high. Festo P.BE-MIDI/MAXI-03-EN en 0209f...
