(1): or yearly, whichever comes first
The indicated oil exchange intervals are valid for standard operating conditions (see section Reference
conditions and limitations ) and nominal operating pressure (see section Compressor data ). Exposure of the
compressor to external pollutants, operation at high humidity combined with low duty cycles or operation at
higher temperatures may require a shorter oil exchange interval. Contact Atlas Copco if in doubt.
Important
• Always consult Atlas Copco if a timer setting has to be changed.
• For the change interval of oil and oil filter in extreme conditions of temperature,
humidity or cooling air, consult your Atlas Copco Customer Centre.
• Any leakage should be attended to immediately. Damaged hoses or flexible joints must
be replaced.
6.2 Oil specifications
It is strongly recommended to use genuine Atlas Copco Lubricants. They are the result of years of field
experience and research. See section Preventive maintenance schedule for the advised replacement intervals
and consult your Spare Parts list for part number information.
Never mix lubricants of different brands or types as they may not be compatible and the
oil mix will have inferior properties. A label, indicating the type of oil filled ex factory, is
stuck on the air receiver/oil tank.
Roto-Inject Fluid
Atlas Copco's Roto-Inject Fluid is a specially developed lubricant for use in single stage oil-injected screw
compressors. Its specific composition keeps the compressor in excellent condition. Roto-Inject Fluid can be
used for compressors operating at ambient temperatures between 0 ˚C (32 ˚F) and 40 ˚C (104 ˚F). If the
compressor is regularly operating in ambient temperatures between 40 °C and 46 °C (115 °F), oil lifetime is
reduced significantly. In such case it is recommended to use Roto-Xtend Duty Fluid.
