10 Lubricant table
Scope The lubricant table applies to all Sauer Compressors intended for
the compression of air.
The lubricant table does not apply to
– Sauer Compressors for the compression of inert, noble or haz-
ardous gases;
– temperature ranges outside of +5 … +55°C.
General
recommendation
We recommend mineral oils of the viscosity class in accordance
with ISO VG 100 for the temperature range 5 … 55°C. The lubri-
cating oils should at least conform to the group VCL in accord-
ance with DIN 51506.
We do not permit the use of synthetic lubrication oils with 2-stage
air-cooled compressors the following reasons:
– The good hydrolytic properties of synthetic oils causes
moisture to condense in the crankcase, risk of corrosion and
drive damage.
– Because of their design, 2-stage air-cooled compressors have
low final compression temperatures, rendering the hight tem-
perature stability of synthetic oils useless.
Note!
The recommended oil types reduce carbonisation in the com-
pressor valves and the connected pipes and fittings to a mini-
mum.
Lubricants not referred to in the lubricant table may only be used
after approval by J.P. SAUER & SOHN. Otherwise the warranty
is void.
Please contact our customer service when selecting oils not
listed or if operating conditions differ from those recommended.
Note!
Unless otherwise ordered, Sauer Compressors are delivered
without oil.
