    (see ISO 8573-1 class 4). You will thereby avoid functional damage of 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-CPA-EN en 0207c...

  • Page 45: 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 viscosity 32cST at 40 °C).
