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.
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).
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).
