8.1 Lubricants and operating materials

8.1.1 Oil recommendation

RC screw compressor air ends must be operated 

with an oil suitable for special requirements. This 

oil must be approved by the lubricant manufac-

turer for screw compressor air ends. It must even 

be suitable under unfavorable operating condi-

tions, 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 air ends on 

request. As oil for screw compressor air ends, 

refined oils (mineral oils) synthetic oils and bio oils 

(biodegradable) can be used as screw compres-

sor oil.

The materials and gaskets used in the screw com-

pressor air end 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 brand and the same oil type 

(see adhesive label on the oil separating tank).

Dropping of the room temperature to below -5°C/

23°F with the compressor stopped should be 

avoided.

8.1.3 Measures at low room temperature

Sufficient room heating.

At an ambient temperature close to freezing point, 

the system must be prevented from freezing by 

installing a standstill heater.

8.1.4 Piping materials

Plastic compressed-air piping systems can be 

attacked by the oil used in the screw compressor 

air ends.

Note:

See the information sheet!

The requirements placed on the cooling oil in the 

screw compressor air ends 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

– viscosity class:

A minimum viscosity of approx. 10 cST at oper-

ating temperature must be ensured

Caution:

Be sure to comply with the oil viscosity, as other-

wise there is a danger for the bearing service life.

Rotorcomp offers optimized and tested EVO-Lube 

oils for screw compressor air ends and recom-

mends their use.
