Description
The 2902022204 is the Atlas Copco Element Spare Part Kit for the 5.5 kW / 8 bar oil-free scroll service stage, and 1616741883 is the element that sits at the centre of it. The two numbers describe one piece of work: the element produces the air, and the kit is the set the parts desk releases for it, with the check valve and the inlet filters that are renewed in the same stop.
Both numbers are recorded against the same machines. The official parts lists show the 2902022204 in the SF 6+, the SF 17+, the SF 22+ and in the QOF 15, QOF 22 and QOF 30, all at 8 bar(e) / 116 psig. That reach is what makes this element one of the busier oil-free scroll part numbers, and it is the reason a single kit number carries it.
This article sets out what the 2902022204 contains, which machines take it, how the 5.5 kW figure relates to the machine the element sits in, how the machine is read before the element is exchanged, and how the order is confirmed.
What the 2902022204 Element Spare Part Kit Is
The 2902022204 is listed as 5.5KW8B ELEMENT SPARE PART KIT in the Atlas Copco parts programme, under the rate group S3M Oil free scroll, Element. It is the exchange set for one 5.5 kW scroll service stage running at 8 bar, and it carries the element together with the parts that sit around it in the air path.
A Service Stage Exchange Set
The item is a set rather than a loose element. The number 1616741883 identifies the element itself, while the 2902022204 identifies the exchange set released for it, and the set is what the parts lists show against the machines.
The difference matters at the point the enquiry is placed. A plant holding the element number has the right part in hand, and the desk confirms it through the set number before the order is written.
The Element the Kit Is Built Around
The element inside is listed as ELEMENT 5,5KW 8 BAR OFSL/E03 under the number 1616741883. It is a serial-numbered part that carries its own nameplate with the part number, the serial number and the country of build, and it arrives in the kit with that plate on it.
Its data sheet reads 580 × 350 × 320 mm and 36 kg, which is the element on its own. The 2902022204 set around it is larger at 660 × 470 × 500 mm and 46 kg, and Belgium is the country of origin recorded for both numbers.
8 Bar and 10 Bar Are Different Numbers
The pressure version is built into the number. The 2902022204 is the 8 bar(e) set that matches the 8 bar(e) / 116 psig machines, while the 10 bar / 145 psig stage carries its own pair of numbers, with the element listed as 1616741882.
An enquiry for a 10 bar machine therefore lands on a different set, and that is the first point the parts desk settles with the model and serial number. The two stages are not interchangeable, and the element number is what separates them.
What the 2902022204 Kit Carries
The set covers the element and the parts that are reached with it, so the unit returns to service in one stop rather than through a sequence of separate part orders.
The 5.5 kW 8 Bar Element
One element, 1616741883, is the core of the 2902022204. It is the compression stage of the machine, the part that takes the drive and delivers the air, and it is renewed as a unit rather than rebuilt in place.
The Check Valve
One check valve, listed as 2236049980, travels in the 2902022204. It sits at the discharge side of the element and holds the pressure line when the machine stops, and it is renewed with the stage because it is reached in the same piece of work.
The Two Air Filter Elements
Two air filter elements, listed as 1613900100, complete the 2902022204. They clean the air before it reaches the scroll element, and they are replaced at the same time so the inlet side is returned with the stage it feeds.
Machines That Take the 2902022204 Element
The element is recorded across two oil-free scroll platforms, the Atlas Copco SF range and the Quincy QOF range, and every machine on the list runs the 8 bar stage.
The SF 6+ and the QOF Range
For the SF 6+ the parts list shows the element and inlet section with the service stage at 8 bar, and the 2902022204 is the kit recorded against it. In the QOF range the 2902022204 is listed for the QOF 15, and again for the QOF 22 and the QOF 30, each at 8 bar(e) / 116 psig.
The SF 17+ and SF 22+ Carry Several Elements
The larger frames are built from more than one element. The parts list gives three elements for the SF 17+ and four for the SF 22+, and those quantities come from the drive arrangement of each model rather than from a calculation on the machine rating.
That changes the way the parts are ordered. A plant running an SF 22+ needs four 1616741883 elements for a full set, which is four 2902022204 kits, while an SF 17+ takes three.
How the 5.5 kW Figure Relates to the Machine
The 5.5 kW in the description belongs to the element, not to the compressor. Oil-free scroll machines of this class are built from identical stages, and the same 5.5 kW element is stacked in different numbers to make machines of different sizes.
One Element Number, Several Machine Sizes
That is why one part number serves a small machine and a large one. The parts list records a single service stage for the SF 6+, three for the SF 17+ and four for the SF 22+, and the spare part the workshop needs is the same item in each case.
The reading is worth keeping when a machine list is set beside a part number, because a 5.5 kW element inside an SF 22+ does not mean the machine is rated at 5.5 kW.
What the Element Does in an Oil-Free Scroll
Inside the element, two intermeshing scrolls trap and compress pockets of air, and the compression chamber runs without oil. That is what gives the machine its oil-free delivery, and it is also why the inlet air is filtered before the element rather than after it.
The orbiting scroll moves while the fixed scroll stays in place, and wear that builds over a long service life shows in the delivery of the stage and in the condition of its bearings. The scroll set is renewed as an element rather than machined back into service, which is why the 2902022204 is supplied as a complete stage.
Reading the Machine Before the Element Is Exchanged
The decision to exchange a stage is taken on the readings of the machine and the hours it has run, not on a single symptom. The numbers are collected at a fixed interval so a trend is visible before the stage is opened.
The Readings That Carry the Decision
Free air delivery at the rated pressure, the discharge temperature at a steady load and the power drawn for each unit of air are the readings that carry the decision. On a scroll stage, delivery that falls while the power holds is the pattern that points to wear in the element.
Vibration and noise at the element and at the drive end are read at the same time. Taken together across a year of operation, the readings tell a plant whether the 2902022204 belongs in the next planned stop.
The Filters and the Valve Around the Element
The parts that arrive with the element have their own read-back. A restricted inlet filter shows in the pressure drop across it, and the check valve shows at the moment the machine stops with a pressure line that does not hold.
Renewing all three positions of the 2902022204 in one stop means the new element is not put behind a filter that is already loaded, and the discharge side is closed with the valve the kit was released with.
The Exchange in Outline
The work divides into three stages, and the 2902022204 covers the parts of all three. Each stage is planned into one stop, so the machine is out of service once rather than twice.
Taking the Stage Out
The machine is isolated and the pressure line vented before anything is opened. The element then comes off its mounts and is carried on its mounting faces from there to the bench, with the pipework and the drive disconnected as the unit is freed.
The old element is kept until the new one from the 2902022204 is confirmed against it. Its plate carries the serial number of the outgoing stage, which is the number that goes into the machine file for that exchange.
Fitting the New Element
The new 1616741883 goes in from the 2902022204, and the check valve and the two air filter elements are fitted as the air path is closed up around it. The plate on the new element is checked against the order before the sealed package is opened.
Cleanliness carries the job at this point more than at any other. The scroll chamber runs to small clearances, and the parts from the kit stay in their packaging until each one is fitted.
Alignment, Coupling and the First Run
With the element in place, the mounting faces are cleaned and checked, the coupling is inspected, and alignment and direction of rotation are confirmed before the machine is turned. The machine is then run unloaded under observation.
Discharge temperature, pressure and the readings at the element and the drive end are watched through the first running period, and the log becomes the baseline for every later check on the 2902022204 job.
Handling the 2902022204 Kit in the Workshop
At 46 kg in a 660 × 470 × 500 mm package, the 2902022204 moves with ordinary workshop equipment. It arrives in a wooden case, and the contents are checked against the line before the job begins.
At the Bench
The 2902022204 stays closed until the machine is safe, the drive is isolated and the work area is ready, and the element is unwrapped at the bench rather than on the floor. The inlet and discharge openings are kept covered through the exchange.
Each part returns to its packaging until it is fitted. A scroll chamber that takes grit at the fitting stage carries that grit for the life of the element.
The Element Nameplate and the Serial Number
The element arrives with its own plate, and the serial number on that plate is written into the machine file when the element goes in. Plants that record the outgoing serial in the same way keep a traceable history of every 2902022204 job on the machine.
The plate also settles the identity of the element against the order at the bench, before a sealed package is opened. It is the last point at which a wrong-number stage is caught with the machine still together.
Ordering the 2902022204 Element Kit
Two numbers settle the order: the element number held by the plant and the set number the exchange kit is released under. The parts desk works between the two with the machine record in hand.
The Number the Parts Desk Records
The element 1616741883 is recorded in the programme with the instruction to order the 2902022204, so the set number is what goes on the order line. A plant that sends the element number reaches the same set, because the two numbers are held as one entry.
What to Send with the Enquiry
Send Seadweer the compressor model and serial number together with whichever of the two numbers is at hand. The team confirms the stage for the machine, the pressure version, and the number of elements the frame carries.
On a frame that runs more than one stage, the quantity is part of the same confirmation, so the enquiry covers the whole machine rather than a single element. The 2902022204 is then quoted with the contents line the workshop will check in.

FAQ
What is the difference between the 2902022204 and the 1616741883?
The 1616741883 is the 5.5 kW / 8 bar oil-free scroll element on its own, and the 2902022204 is the exchange kit released for it. The kit carries one element together with the check valve and two air filter elements.
Which machines take the 2902022204 element kit?
The official parts lists record it for the SF 6+, the SF 17+, the SF 22+ and the QOF 15, QOF 22 and QOF 30, all at 8 bar(e) / 116 psig. The SF 17+ carries three elements and the SF 22+ carries four.
What is inside the 2902022204 kit?
The set holds one element 1616741883, one check valve 2236049980 and two air filter elements 1613900100. All three positions are reached in the same piece of work, so the stage returns to service in one stop.
Is 5.5 kW the rating of the compressor?
No. The 5.5 kW belongs to the element, and the larger frames are built from several of those stages, with three elements recorded for the SF 17+ and four for the SF 22+. A 5.5 kW element inside a larger machine does not make that machine a 5.5 kW unit.
Does the 2902022204 cover the 10 bar machine?
No. The 2902022204 is the 8 bar(e) / 116 psig set, and the 10 bar stage carries its own element and kit numbers. Send the model and serial number and the pressure version is confirmed from the machine record.
How is the 2902022204 element kit ordered?
The element number is held in the programme with the instruction to order the set number, so the 2902022204 is what goes on the order line. Send Seadweer the compressor model and serial number and the parts desk confirms the set for the frame.

Ngozi Okafor –
We hold the 1616741883 number for the scroll element, and the parts line came back with the 2902022204 set instead. The kit arrived complete, with the check valve and the two air filter elements on the contents line, and the element plate was checked against the order before the old stage came off. Both units on that frame have held their discharge temperature at the level we log after an element exchange, and the element serial number is now on the machine file with the date of the stop.
