  • Page 50: Preparing The Compressed Air

    If possible, operate your system with non−lubricated com pressed air. This will prevent pollution of the environment. Festo pneumatic valves and cylinders have been designed so that, if used as intended, they will not require additional lu brication and will still achieve a long service life.
  • Page 51 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 32cST at 40 °C).
  • Page 52 A further indication of excessive lubrication is the colouring 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. 3−6 Festo P.BE−MPA−EN en 0302NH...
