Atlas Copco's Roto-Foodgrade Fluid is a unique high quality synthetic lubricant, specially created for oil- injected screw compressors that provide air for the food industry.

This lubricant keeps the compressor in excellent condition. Roto-Foodgrade 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

Select the ambient temperature range

Select the element outlet temperature range

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

Ambient temperature - up to 25 °C -- Element outlet temperature - up to 90 °C: Exchange interval is 4000 Hours / 1 Year

Ambient temperature - from 25 °C up to 35 °C -- Element outlet temperature - from 90 °C up to 100 °C: Exchange interval is 3000 Hours / 1 Year

Ambient temperature - more than 35 °C -- Element outlet temperature - more than 100 °C: Exchange interval is 2000 Hours / 1 Year

Check oil level. If needed, top up the oil

Check that condensate is discharged during operation

NOTE! The safety valve (SV) test can only be performed by authorized personnel and is protected by a security code

WARNING! No adjustments are allowed. Never run the compressor without safety valve

Enter the set pressure stamped on the valve

Did the safety valve open at the set pressure?

Does the safety valve need to be replaced?

Warning: This procedure requires trained personnel with PPE!

Is the compressor operating in ambient temperatures above 40 °C (104 °F)?

If the compressor is regularly operating in ambient temperatures above 40 °C (104 °F), oil lifetime is reduced.
