3.1

Compressed air preparation

Note

Unfiltered or incorrectly lubricated compressed air will
reduce the service life of the valve terminal.

3.1.1 Operation with unlubricated compressed air

Note

Too much residual oil content in the compressed air will
reduce the service life of the valve terminal.

– If bio oils are used (oils based on synthetic esters or nat-

ive esters, e.g. rapeseed oil methylic ester), the residual
oil content must not exceed max. 0.1 mg/m

(see ISO

8573-1 class 2).

– If mineral oils are used (e.g. HLP oils to DIN 51524 Part 1

to 3) or corresponding oils based on polyalphaolefin
(PAO), the residual oil content must not exceed 5 mg/m

(see ISO 8573-1 class 4).

This avoids operative malfunction of the valves.

Excessive residual oil is not permissible irrespective of the
compressor oil, as otherwise the basic lubrication will be
washed out with time.
