Caution
Dirty or incorrectly lubricated compressed air will reduce
the service life of the valve terminal.
Caution
Excessive residual oil in the compressed air will reduce the
service life of the valve terminal.
– If bio oil is used (oils based on synthetic ester or true
ester, e.g. rape oil methyl ester), the residual oil content
must not exceed 0.1 mg/m² (see ISO 8573-1 class 2).
– If mineral oils are used (e.g. HLP oils as per DIN 51524
parts 1 to 3) or corresponding oils on the basis of poly-
alphaolefin (PAO), the residual oil content must not ex-
ceed 5 mg/m² (see ISO 8573-1 class 4).
In this way you will avoid functional damage to the valves.
A higher amount of residual oil cannot be permitted irrespec-
tive of the compressor oil, as otherwise the basic lubricating
oil will be washed out in the course of time.
