Atlas Copco OEM 1622314001 Screw Compressor Air Oil Separator

Causes of failures/ apparent failures

• Scavenge line too short

Scavenge line does not reach into internal bowl at the base of the separator.

Result: high oil carry over

• Scavenge line too long

End of scavenge line seats against base of bowl forming a seal. No oil, or an insufficient quantity is sucked up by the scavenge line. Compressor manufacturer’s gap clearance is normally 1 to 2 mm alternatively, ensure tapered cut to end of scavenge line.

Result: high oil carry over

• Scavenge line blocked with dirt

Result: high oil carry over

• Scavenge line filter blocked

Some compressor models are fitted wit a small stainless steel mesh filter at some point in the scavenge line which is to be cleaned on a regular basis. If not cleaned the filter will block resulting in no scavenge action.

Result: high oil carry over.

• Scavenge line cracked / damaged

Allows atmospheric air to be ingested and insufficient or no oil removed from separator.

Result: high oil carry over.
