Hey! This site is reader-supported and we earn commissions if you purchase products from retailers after clicking on a link from our site.

Welcome to the world of Atlas Copco compressors their website boasts.

That is a valid statement considering that Atlas Copco has been in the business of air compressor and industrial equipment for over 100 years, and their products and services are available in dozens and dozens of countries around the world.

Unlike some other major air compressors, Atlas Copco is seriously in the business of providing rental air compressors, air compressors that can be acquired for a specific project, and then returned when the need for that expensive piece of capital equipment is over.

For those applications requiring Oil-Free compressed air, Atlas Copco has solutions. For other industrial needs, they offer a broad range of Oil-Lubricated air compressors.

You can acquire a reciprocating (piston) air compressor from Atlas Copco, or they offer a broad range of rotary screw type compressors as well. Typically, their line of tow-behind (portable) air compressors, with a range of power supplies, are of the rotary screw design.

Fix My Compressor - Atlas Copco Portable Compressor

This Fix My Compressor site was conceived originally to help folks with their home or small workshop air compressors. We are finding that folks are posting questions about all kinds of air compressors, including the Atlas Copco compressors line.

The logical first step if you are having a problem with your Atlas Copco air compressor is to contact them: Their American customer service team can be contacted at 800-732-6762 or accmt.acconnect@us.atlascopco.com. Visiting their site will provide contact info for other offices around the world.

The folks behind this Fix My Compressor website are not experts in the use or maintenance of the tow behind  portable air compressor. Many folks are, however.  Questions posed about any problems with the Atlas Copco air compressor will be found at the bottom of this page. We invite you to help users of these compressors whenever you can by adding your advice to the questions below. Of course, if you have a question, feel free to post it as well.

If it’s pulling in air and the tank is not building pressure, where’s the air going? There must be an open outlet somewhere, that or the screw isn’t working. Sorry I can’t be of any real help.

Anyone else with a G7 from Atlas Copco can offer any suggestions for Joseph?

Please, I have a GA30P compressor. The problem is I bought a new module for it, but the module isn’t coming up. No light on it, but there is a 115V and 24V supply getting to it.

Wajjid, on #3, did you check that oil can actually flow thru there? The thermostat should allow it, but maybe there’s a clog somewhere. The radiator should get warm to hot. Does it?

Sir radiator is cool. Infact oil Filter and separate tank all cool. Only heat is generate under compressor element line which is going to seperator tank and temperature sensor is fitted on this line. I already check and clean radiator . No blockage in cooler.

Well, somethings not pushing the oil.
Does it make any pressure before it shuts down?

Yes sir it building pressure upto 4.8 bar and then stop due to high temperature. I am using Atlas Capco GA 22 . Is it valve fitted in between compressor discharge line to seperator tank inlet line. Because temperature start raising from there.
Thanks

Yeah, I presume you should be getting to around 7 bar. That it stops at 4.8 suggests the minimum pressure valve is open before it should be. Maybe stuck.
You should probably have 7 bar in less than ten seconds.

Please check oil stop valve/ check valve it might be stuck somewhere in open/close position.
Service / replace both of them hopefully it will work for you. Thanks!

I posted on one of the other pages to see if you knew what the compressor is I have just been given, but I have just found a tag saying it is a atlas copco PE4 compressor. It is not a tow behind type though? I was hoping if anyone can give me any information about this type of machine and what part is what as I would love to restore it and where can I get parts that would fit this.
Thanks

If it’s not starting, and you’ve got correct power, then it’s the pressure switch / unloader that’s likely preventing power getting to the motor. I’m puzzled though… if it’s new, what does Atlas Copco support say?

I have problem in compressor Atlas Copco ZT110 (220Amp)Free oil type that when compressor motor change from star to delta and delta contactor energized immediately the main circuit breaker tripped, while there was no up normal sound and coupling between compressor and motor is turning smoothly.
We suspected that we had problem in motor control, we checked it’s ok . also we changed the main circuit breaker, make insulation test
for cable from C/B to compressor it’s Ok.
In a compressor side we changed the check valve and make check for the inlet valve function it’s Ok.
Finally we disconnected the coupling of compressor and run motor alone it running well without C/B trip, line Ampere is 37A.
Please Advice..

I have a Atlas Copco xavs400cd7 that we have been having trouble with. It is very hard to start but after you get it started it seems to run fine you can load the compressor fine, but when you go to unload you press the unload button and instead of unloading it will go to cooldown mode and shut the unit off. We have tried a different controler that didn’t help,installed new engine ecm and we thought that fixed the problem it worked fine about 15 to20 times as soon as it went out into service it started doing the same thing again.

I have a “XRVS 1000 CD6 t4i” (1547hrs, S/N APP248683) that will not build tank psi. the engine sits at 1300rpm and loads at 1800rpm, when it thinks its loaded it goes back to 1300rpm, when it says loaded I never heard it load the tank. the screen tells me there is 88psi, when I open the ball valve there is no air. im not familiar with atlas copco, any info would be greatly appreciated. thanks in advance.

I have a Atlas Copco rotary screw air compressor and it starts and runs fine, but occasionally it loads air or unloads and starts whining and I have to go and flip the switch to unload and back again to make it stop. This is usually only a couple times in an 8 hour period but would like to fix before it gets worse. Also this compressor is now a backup so only runs once a week. Thanks
