Atlas Copco Compressor → Controller Compatibility Chart
A plain-English guide to which controller generation typically goes on which Atlas Copco compressor. Use it to narrow down the right family — then confirm the exact part number by machine serial.
Stationary compressors — Elektronikon
| Compressor family | Typical controller generation(s) | Notes |
|---|---|---|
| GA screw (fixed speed), 1990s–2000s | Elektronikon I / II (legacy) | Early mono/segment regulators; base & graphic variants |
| GA fixed speed, ~mid-2000s–2010s | Elektronikon Mk4 (Base / Graphic) | Cutover year varies by GA size & market |
| GA fixed speed, current | Mk5 Graphic / Touch / Graphic Plus / Mk5S | Touch screen ~41% larger than Graphic |
| GA VSD / VSD+ (variable speed) | Same generation as the fixed-speed GA of that era, VSD-configured | Adds RS485 link to the drive |
| GX / small screw | Elektronikon Graphic; Elektronikon Nano on the smallest | Small GX serials may ship a base tier |
| ZR / ZT oil-free screw (& VSD) | Same era as contemporaneous GA (Mk4 → Mk5 Graphic/Touch) | Oil-free units usually get the Graphic/Touch tier |
| FD refrigerant dryers | Elektronikon Alpha (basic) or optional Graphic | Distinct dryer module set, not a compressor Elektronikon |
Browse stationary stock by generation: Elektronikon I & II, Mk5, Mk5 Graphic, Mk5S Touch & Swipe.
Portable diesel compressors — Xc family
The leading digit of an Xc controller is the size class (1 small → 4 large / boosters); the trailing digits are the generation (…02 older, …03 middle, …04 current). Full detail in the Xc portable controllers guide.
| Xc controller | Class | Typical portable ranges |
|---|---|---|
| Xc1002 | Small, older gen | Small XAS single-pressure portables |
| Xc2002 | Mid, older gen | Mid/large XAS / XAMS / XATS / XAHS / XAVS (aftermarket-listed — confirm by serial) |
| Xc2003 | Mid, current gen | "Versatility" range ~200–600 cfm; adds PACE variable pressure & ECO-mode |
| Xc3003 | Large, middle gen | Large single/mid-stage portables (PARUS 3 firmware) |
| Xc4004 | Large, current gen | Boosters, DrillAir and large machines; 7" IP67 display; replaces seven older controllers |
Frequently asked questions
Which controller fits an Atlas Copco GA compressor?
It depends on the age of the GA. Older GA units used Elektronikon I / II, mid-generation units used Mk4 or Mk5 Graphic, and current GA / GA VSD+ machines use Mk5 Touch or Mk5S. Because fitment follows the machine build, confirm the exact part number against your GA's serial number.
Can I use an Elektronikon controller on a portable Atlas Copco compressor?
No. Stationary compressors (GA, GX, ZR/ZT) use Elektronikon controllers, while portable diesel machines (XAS, XATS, XAHS) use the Xc controller family. The two are separate systems and are not interchangeable.
How do I know the exact controller part number for my machine?
The controller is matched to the machine by its loaded software, so the correct part depends on the compressor serial number and build. Send us your model and serial and we confirm the exact part, including any superseded or replacement number.
