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.
7.2 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.
Avoid mixing lubricants of different brands or types as they may not be compatible and
the oil mix may 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 above 35 °C (95 °F), oil lifetime is reduced
significantly. In such case use Roto-Xtend Duty Fluid for a longer interval for oil exchange.
If the compressor is regularly operating in ambient temperatures above 35 °C (95 °F), oil lifetime is
reduced (see table oil lifetime Preventive maintenance schedule).
Roto-Xtend Duty Fluid
Atlas Copco's Roto-Xtend Duty Fluid is a high quality synthetic lubricant for oil injected screw
compressors which keeps the compressor in excellent condition. Because of its excellent oxidation
stability, Roto-Xtend Duty Fluid can be used for compressors operating at ambient temperatures between 0
˚C (32 ˚F) and 46 ˚C (115 ˚F).
Roto-Xtend Duty Fluid is the standard oil for compressors equipped with freeze protection.
If the compressor is regularly operating in ambient temperatures above 40 °C (104 °F), oil lifetime is
reduced (see table oil lifetime Preventive maintenance schedule).
