Always drain the compressor oil at all drain points. Used oil left in the compressor can contaminate the oil system and can shorten the lifetime of the new oil

Never mix lubricants of different brands or types as they may not be compatible and the oil mix will have inferior properties. A label, indicating the type of oil filled ex-factory, is stuck on the air receiver/oil tank

Run the compressor until warm and stop the compressor

Close the air outlet valve and switch off the voltage

Wait 3 minutes for the compressor to depressurise the vessel

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

Warning: This procedure requires trained personnel with PPE!
