8.1 Lubricants and operating materials
8.1.1 Oil recommendation
RC screw compressors must be operated with an
oil suitable for special requirements. This oil must
be approved by the manufacturer for screw com-
pressors. It must even be suitable under unfavor-
able operating conditions, such as soiling of the
intake air with gases, solvent vapors and exhaust
gases and at high ambient temperatures.
Suitable oil types and oil manufacturers can be
specified for screw compressor on request.
Refined oils (mineral oils) synthetic oils and bio
oils (biodegradable) can be used as screw com-
pressor oil.
The materials and gaskets used in the screw com-
pressor system must be taken into account when
selecting the oil type. Corrosion and other material
damage may not occur.
It is not permissible to mix different oils.
8.1.2 Topping up oil
Use the same manufacturer and the same oil type
as is currently in use in the screw compressor.
8.1.3 Measures at low room temperature
Sufficient room heating.
At ambient temperatures below 0°C/32°F, the sys-
tem must be heated up to at least 20°C/68°F
before start-up with an integrated standstill heater.
8.1.4 Piping materials
Plastic compressed-air piping systems can be
attacked by the oil used in the screw compressor.

Note:
See the information sheet!
The requirements placed on the cooling oil in the
screw compressor include the following:
– High resistance to aging
– High dispersive power
– Flash point: over 200°C/392°F
– Minimum foaming
– High corrosion protection
– Operating temperature: up to 110°C/230°F
– Select suitable viscosity class, e.g. ISO VG 68.
e
Caution:
Be sure to comply with the oil viscosity, as other-
wise there is a danger for the bearing service life.
