Description
The 1616884190 is the SERVICE AIREND OIS O-06, the oil-injected screw element Atlas Copco records for the GA 90+, GA 110, GA 132 and GA 160 compressors and for the VSD+ builds of the same series. It is the current reference of a three-number chain: the position began as the 1616884180 C200 OIS O-06, the 1616884190 carries it as the ordering reference today, and units are supplied on the newest build of the line.
At 430.00 kg and an 82 × 59 × 55 cm envelope, this is a crane-class renewal rather than a two-person lift, and the figures are published so the lift can be planned before the order is placed. The housing plate reads the production number 1810015580 with a MADE IN CHINA marking. This article sets out what the O-06 designation covers, how the chain of numbers resolves, which machines take the stage, and how fitment is confirmed before an order is placed.
Identity of the 1616884190 Element
An element is the core compression stage of a screw compressor, and the 1616884190 fills that role as the O-06 stage of the oil-injected GA programme. It converts shaft power into air flow at pressure, and it is a long-life factory assembly: the rotor pair, the housing and the bearings are built as one and renewed as one.
The interfaces of that assembly are set by the machines it was built for, which is why the 1616884190 is confirmed against a compressor record rather than against a description.
What the OIS O-06 Designation Covers
OIS is the oil-injected screw designation, and O-06 is the stage code Atlas Copco records for this element. The earliest version of the position carried the name C200 OIS O-06, and the current item record names it SERVICE AIREND OIS O-06; the code O-06 runs through both names and marks the same compression stage.
Atlas Copco prints the number in two forms. The ten-digit form 1616884190 is what the item record carries, and 1616 8841 90 is the printed form used across the parts documents. Both name the same stage, and either one works when a renewal is being confirmed.
The Production Number on the Housing Plate
The plate on the housing reads 1810015580, the production number of the unit, together with a serial of its own and a MADE IN CHINA marking. The number follows the pairing Atlas Copco uses across this element family: 1810015580 on the plate is the production counterpart of 1810015590, the newest build in the chain that the 1616884190 position is supplied on.
That pairing is worth keeping straight in the machine file. A fitter reading the plate and a planner reading the spares list quote different numbers for the same position, and knowing both ends the confusion before it starts. Seadweer confirms the pairing against the parts records when an enquiry is handled.
The Chain From 1616884180 to 1810015590
The O-06 stage has been renumbered twice in its life, and every record in the machine file resolves to the same position. The table below collects the chain in one place.
| Number | Role today |
| 1616884180 | C200 OIS O-06, the earliest version of the stage |
| 1616884190 | SERVICE AIREND OIS O-06, the current ordering reference |
| 1810015590 | The newest build supplied against the 1616884190 position |
Reading the Chain in a Machine File
The strongest single record for the chain comes from a machine file. The parts list of a GA 132 built under serial WUX418919 lists 1616884180, C200 OIS O-06, in its element section and notes it as substituted by 1616884190, SERVICE AIREND OIS O-06. That is the manufacturer resolving the old number to the current one on a specific machine, not a suggestion from a catalogue.
The same parts list documentation carries the 1616884190 as ELEMENT COMPR. with a validity running from 21/02/2018 to 31/12/2040, so the ordering reference is stable for the service life of the machines it covers. Orders placed against 1616884180 are directed to the current reference in one pass.
The Nipple for the First Fitment
Atlas Copco’s item record carries a fitting note for the chain: when the element 1616884190 is replaced for the first time by the element 1810015590, the nipple 1830080852 is ordered with it to connect the Extra Oil Injection hose to the new element.
The note matters for planning. A first-time renewal that arrives without the nipple stops halfway through the job, and the hose connection is the one interface the new build changes. Seadweer flags 1830080852 with the quotation for every first-time fitment of the 1616884190, so the fitting day runs to the end.
Compressors That Take the 1616884190
Atlas Copco’s official parts list No. 2930 1915 00, Edition 5, records the 1616884190 in its compressor element section, and the machine range of that documentation is explicit. The documented coverage falls into two groups, collected in the table below.
| Group | Documented units |
| Fixed-speed GA series | GA 90+, GA 110, GA 132, GA 160 |
| VSD+ builds | GA 110 VSD+, GA 132 VSD+, GA 160 VSD+ |
The Fixed-Speed GA Series
The GA 90+, GA 110, GA 132 and GA 160 are the large oil-injected workhorses of the stationary range, and the official documentation ties the 1616884190 to all four through the same parts list. One stage number across the four frame sizes simplifies the spares position of a plant that runs several of them side by side.
For each of these machines the element is the component the whole output rests on, and the O-06 stage is the position the parts list names for it.
The VSD+ Builds
The documentation covers the VSD+ builds of the same series: GA 110 VSD+, GA 132 VSD+ and GA 160 VSD+. The variable-speed drive changes how the machine modulates, and the element underneath stays the O-06 position documented in the same parts list.
A fleet that mixes fixed-speed and VSD+ machines in these frame sizes can therefore hold one element reference for both, and the 1616884190 is that reference.
Why Fitment Is Confirmed per Machine
The documented range stops where the documentation stops. The parts list names the seven models above, and no other frame sizes are added to the record by inference: the element position of a given machine is settled by the parts list for its serial number, not by the family name on the canopy.
That is why the 1616884190 is confirmed from the machine nameplate and the old element number together. Two machines under the same series name sit on different generations, and the check is what keeps the wrong box off the workshop floor.
What the Oil-Injected Screw Element Does
Oil-injected compression starts from a condition the O-06 is built around: oil is fed into the compression chamber of the 1616884190 and does three jobs at once — it seals the running clearances, it lubricates the rotors and it carries heat away.
The Oil Film and the Rotor Pair
The rotor pair turns in a precision-bored housing with the oil film sealing the gaps between the lobes, so the pockets hold pressure as they travel from the inlet to the discharge port. Because the oil carries the sealing and the cooling, the stage runs cooler than a dry chamber would and the rotors ride in a protected environment.
Precision rolling bearings take the radial and thrust loads of the shafts, and the oil separated out downstream returns to the circuit. Everything about the air path after the stage — separators, filters, dryers — is sized around the oil that the 1616884190 injects, which is why a stage in good condition is also an oil-carry-over decision.
A Complete Factory Assembly
The 1616884190 is renewed as a complete unit rather than rebuilt in place. The rotor pair, the housing and the bearings arrive as one factory assembly with the ports and the drive interface set for the machines it serves.
That is what makes the renewal a planned swap instead of a workshop project: the old stage comes out, the new one goes in on its mounting faces, and the machine returns to its log with a fresh serial to record.
Handling the 430 kg Stage
At 430.00 kg and 82 × 59 × 55 cm, the 1616884190 is crane-only territory: well above the two-person lift class, and light enough for a standard workshop gantry or a mobile engine crane rated for the mass. The figures describe the unit as it is supplied, and they shape the route from the unloading point to the machine.
Dimensions and Lifting Plan
The 82 × 59 × 55 cm envelope reaches the site on a pallet, and the openings it has to pass are measured in advance: doorway widths, gantry height and the standing room in front of the machine. A crane or gantry rated for the 430.00 kg of the 1616884190 covers the lift, and the slinging keeps the load level through the move.
The stage is carried on its mounting faces and never on its shaft. Port caps stay in place until the moment of fitment, so nothing reaches the bore while the unit is exposed.
Setting Down and the First Run
Before the machine is closed up, the mounting faces are cleaned and checked for burrs, the coupling is inspected for wear, and alignment and direction of rotation are confirmed. On a first-time fitment of the newest build, the Extra Oil Injection hose is connected through the nipple 1830080852 at this stage of the job.
Once running, the machine is brought up unloaded and watched while the readings settle. Discharge temperature, pressure and vibration are logged through the first running period, and fasteners are re-torqued after the first hours. That short log becomes the baseline for every later check on the 1616884190.
Wear Signs and Renewal Timing
Renewal of the 1616884190 is decided on condition rather than on a fixed hour count. Two lines of evidence carry most of that decision, and both read best as trends taken at a fixed interval rather than as single figures.
Possible Warning Signs
The rotor surfaces and the bearings are what change first. As they wear, the running clearances open and the stage delivers less air at the same shaft power, so a falling free air delivery measured at the rated pressure is the reading that follows that change. Discharge temperature at a steady load moves with it.
Three further readings carry the same story:
- More power drawn for each unit of air delivered at a steady load, which separates a worn 1616884190 from a machine whose demand has changed.
- Vibration at the bearing housings, read at a fixed interval so the level forms a trend rather than a single figure.
- Rising oil carry-over downstream, which moves with the internal condition of the stage and shows up at the separator first.
Timing the Renewal
Left unchecked, bearing wear can end with the rotors contacting, and at that point the stage is written off rather than renewed. A planned renewal avoids that outcome, because the unit is changed while the frame, the drive and the pipework are still in good order.
The serial recorded in the machine file is what makes that timing judgement easier, since it ties the readings to a known stage rather than to a model in general.
Ordering the 1616884190 Through Seadweer
Two pieces of information lock the order down: the number on the element being renewed — whether it reads 1616884190, 1810015580 on the plate, or the earlier 1616884180 — and the model and serial number from the compressor nameplate.
Machine Record Check
Send both to Seadweer and the parts desk checks the number against the machine record and confirms the 1616884190 in one pass. Where the number on the old element has worn away, the nameplate is enough on its own, because the parts list for the machine names the element it was built with.
Plants that run several GA machines keep a short record for each unit: model, serial number and element number. That record turns the next enquiry into a single message with a confirmed answer, and it is the same record the parts desk works from when the 1616884190 is quoted.
What the Quotation Confirms
The quotation repeats the item data of the 1616884190: the SERVICE AIREND OIS O-06 designation, the packed size, the weight, the country of origin and the tariff code, together with the nipple 1830080852 where the fitment is a first-time replacement. One confirmation covers the whole renewal, so the workshop plans the lift and the stop without a second enquiry for the same stage.
Send the machine details with the enquiry and the answer comes back with the fitment already checked. That is the whole of the ordering process for a 1616884190 renewal.

FAQ
What is the 1616884190?
The 1616884190 is the SERVICE AIREND OIS O-06, the oil-injected screw element Atlas Copco records for the GA 90+, GA 110, GA 132 and GA 160 compressors and the VSD+ builds of the same series. It is a complete factory assembly renewed as a unit rather than rebuilt in place.
What is the difference between 1616884190 and 1810015580?
They name one and the same stage. 1810015580 is the production number on the housing plate, and the 1616884190 is the reference the parts records and orders are written against.
My machine file carries 1616884180 — which number is current?
1616884180 is the earliest version of the stage, named C200 OIS O-06, and it resolves to the 1616884190. The parts list of a GA 132 under serial WUX418919 documents exactly that substitution.
Which compressors take the 1616884190?
The official parts list No. 2930 1915 00 covers GA 90+, GA 110, GA 132 and GA 160 and the VSD+ builds GA 110 VSD+, GA 132 VSD+ and GA 160 VSD+. Fitment for a specific machine is confirmed from its serial number record.
Why does the first renewal need a nipple?
When the element 1616884190 is replaced for the first time by the element 1810015590, the nipple 1830080852 is required to connect the Extra Oil Injection hose to the new element. It is ordered with the stage so the fitting day runs to the end.
How heavy is the 1616884190?
The item data lists 430.00 kg in an 82 × 59 × 55 cm envelope, so the lift is planned with a crane or gantry rated for that mass. The 1616884190 is carried on its mounting faces and never on its shaft.

Tomás Herrera –
Our drawings carried the C200 number, the spares list carried the O-06 service number, and nobody in the workshop could say which one to quote. Seadweer settled it in one reply with the full chain and the note about the nipple for the first fitment, which we would never have thought to order. The stage arrived at 430 kg exactly as stated, the plate matched the paperwork, and the crane plan we made from the published figures held without a change. That is how a major renewal should run.
