The Atlas Copco 3001-5311-06 Oil Separator Kit (A-D Vessel) is one of several vessel-specific separator kits Atlas Copco offers for its large stationary compressors — parallel kits exist for B, C, and H vessel configurations (part nos. 3001531107, 3001531108, 3001531109). “A-D Vessel” refers to the receiver/separator vessel size classification rather than a specific compressor model, so confirming your compressor’s vessel designation matters when ordering, not just its GA model number.
Its part number sits within the same catalog block as the GA160+-315 8,000-hour and 16,000-hour service kits (3001531104/3001531105), consistent with its role as the A-D vessel separator kit for that compressor family.Atlas Copco parts catalog data groups this kit alongside service kits explicitly labeled for the GA160+-315 (VSD) range — a genuine Atlas Copco product family (160-315 kW stationary compressors) — though we’d recommend confirming this against your compressor’s own documentation given the value of this component.

Pressure Differential
Watch the Pressure Differentia l,Not Just the Calendar
Oil separators are rated for a specific pressure drop (ΔP) across the e lement.As the element loads up with oil and particulate over time,this differential rises — most compressors with a differential pressure gauge or sensor will show this directly,and it ‘s a far more reliable replacement trigger than a fixed time interval,since the rate of loading depends on oil consumption and duty cycle.Waiting until the differential hits a warning threshold,rather than guessing based on hours alone,avoids both premature replacement and running an element too long.
Don 't Run Past End-of-Life
Running Past the Rated Life Isn ‘t a Cost Saving
An oil separator element that ‘s well past its rated life doesn ‘t just lose efficiency — the element material itself degrades, and in some cases can rupture under continued pressure load,releasing a larger volume of oil into the air system at once rather than a gradual increase in carryover.The apparent savings from stretching the replacement interval rarely offset the cost of cleaning up a downstream oil contamination event.
If Oil Consumption Rises but the Separator Element Looks Fine
The separator element isn ‘t the only part of the system responsible for oil carryover.A scavenge line (the small return path that channels collected oil back into the lubrication circuit) can become blocked or its check valve can fail — when this happens,oil that the element successfully separated doesn ‘t return to circulation,and carryover can persist even with a element in good condition.If you ‘ve replaced the element and oil consumption hasn ‘t improved, checking the scavenge line and its orifice/check valve is the next place to look before assuming the new element is defective.
Common Questions
How do I know if my oil separator needs replacing?
Rising pressure differential (if your compressor has a gauge) is the most reliable indicator.Visible oil in the compressed air line,or a noticeable increase in oil consumption,are also signs worth investigating.
What 's the difference between an oil filter and an oil separator?
The oil filter cleans the lubricating oil circulating through the compressor.The oil separator removes oil that ‘s mixed into the compressed air stream after compression — they serve different stages of the same system.
Can a failing separator damage anything downstream?
Yes — oil carryover can affect pneumatic tools,spray equipment,or any process that relies on clean compressed air.
Are these genuine Atlas Copco parts?
Yes.Parts are sourced through Atlas Copco distributor channels.
What is the typical lead time?
Common consumables (filters, oil) typically ship within about 1 week. Lead time for other spare parts depends on stock availability — please contact us for a confirmed schedule.
Do you inspect parts before shipment?
Yes. We provide full photos and video of the actual item before shipment, and confirm everything is correct with you prior to dispatch.
What shipping options are available?
If you have your own freight forwarder, we can ship to them directly. If not, we can provide shipping options based on your preference.
