Roto Synthetic Fluid ULTRA
Roto Synthetic Fluid ULTRA is a synthetic oil based 4000 hours lubricant, specially developed for
use in single stage oil injected screw compressors running in demanding conditions. Roto
Synthetic Fluid ULTRA can be used for compressors operating at ambient temperatures between
0 ˚C (32 ˚F) and 45 ˚C (113 ˚F). For more extreme conditions, or when longer oil life is required, it
is recommended to use Roto Synthetic Fluid XTEND DUTY.
Roto Synthetic Fluid XTEND DUTY
Atlas Copco's Roto Synthetic Fluid XTEND DUTY is a high quality synthetic 8000 hours lubricant
for oil injected screw compressors which keeps the compressor in excellent condition. Because
of its excellent oxidation stability, Roto Synthetic Fluid XTEND DUTY can be used for
compressors operating at ambient temperatures between 0 ˚C (32 ˚F) and 46 ˚C (115 ˚F). Roto
Synthetic Fluid XTEND DUTY is the standard lubricant for oil injected screw compressors
equipped with freeze protection or Energy Recovery.
If the compressor is regularly operating in ambient temperatures above 40 °C (104 °F), oil lifetime
is reduced (see table oil lifetime
