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.

Select the ambient temperature range

Select the element outlet temperature range

Based on the selected temperature ranges, follow the appropriate exchange interval.

Warning: Ensure the compressor is stopped, the air outlet valve is closed and the voltage is switched off before starting the procedure.
