What oil should I use in a Gardner Denver ADD-1011 compressor?

It’s obviously out of warranty, so any compressor oil should do.
You can try a non-detergent full synthetic if you want. 20w or maybe 30 if it’s got a lot of hours on it.
What is the rated pressure on it? Just curious.

It was used when I got it, I’ve had it for a number of years. It’s the main shop compressor and runs a large bead blast cabinet plus spray mist coolant on several machines…….so yeah, lots of hours. 175psi @ 770rpm

Seems to be a great pump. I’d be inclined to go synthetic. G-D sells it, but you can probably beat their price, if price matters to you.
I suggest you change it, run it for a day or two, then change it again if you switch.
There’s even a rebuild kit available, if you need it.

I have an Gardner Denver air compressor model ABC 100 to is it worth anything

Yes. How much? Depends on its condition and where you are located. Folks typically won’t buy a compressor that’s a long way away due to packing and shipping costs. Perhaps you might add a comment letting us know if it works, some history on it if you have it, and what city you are located in.

I have a Gardner Denver model AAB-8 2 cylinder, water cooled, pressure lubricated compressor and am looking for any information so I can get it working. It came from a felt factory and was probably run by an electric motor (maybe 220 volt?). I plan to run it with a vintage throttle governed gas engine with clutch. What I would really like are some pictures or operating instructions/manuals. Thanks in advance for any help!

How ’bout posting the tag or whatever tells you it’s Gardner Denver model AAB-8?
Maybe even whole unit while you’re at it.

Sorry the model number was wrong. My son sent me the pictures and the model # is AAB-1002.

Well, sorry, still can’t find anything useful. However, based on the plate, looks like it could make right around 5CFM, and probably needs a 7.5 HP motor to get to 150PSI. 15 or so with your engine. It looks like the openings at the top of the cylinders may be for an unloader system to allow continuous run, so you may be able to do away with the clutch if you can figure out how they work. Maybe someone else can tell you more now that we have pix. Good luck, and please do let us know if you find… Read more »

Gardner Denver TAMROTOR Compressor screw compressor ..when i start in few second go to high temp ..after that intake valve to hot and smoking ! !!

Got oil? This happens from COLD start?
What have you got – just a tamrotor airend, or which of the packages?
Finally, have you seen it work properly in the past?

Yes was working gook , oil ok , it s tamrotor ES37 water cooled Garden Denver , but what i saw the intake vv it s opening to much if u compare whit another compressor what it s in use , and start steaming the intake vv after stop , Fw temp IN32 OUT42 same like another one ! On the oil sight glass u can see moisture of like fog !

After three cycle it s going on 115 degree and stop

Sounds like your Minimum Pressure Valve may be stuck open. They normally open around 50 psi. To get oil on the intake, you need pressure. The intake is wide open trying to get some air and make pressure. No (or low) pressure = no oil = overheats = smoke. I think if you check one of the other machines from a cold start, you’ll see the intake on that go wide open briefly and then either close or go very small as soon as there is pressure. By the way, where are you located and is this out of warranty?… Read more »

I m on the ship !
No more warranty , i can t make oil to lubricate … outlet hose from screw it hot but nothing it a coming to inlet ! Still cold … nothing passing …

Did you check the MPV?
You say:
” i can t make oil to lubricate …” and from a previous post “On the oil sight glass u can see moisture of like fog !”
Those quotes make it sound like it needs oil in addition to pressure.
Are you saying you have no oil on board for it? Then maybe someone wasn’t doing their job.
If you have other working machines, perhaps you could drain a bit from them to put in the problem machine. But you should check that MPV before anything else.


Seguramente no estás utilizando el aceite adecuado.

Independientemente de esto si el compresor no se detiene por alta temperatura, no deberías tener problemas.

traductor Google:

You are probably not using the right oil.

Regardless of this if the compressor does not stop due to high temperature, you should not have problems.

i have a ACD -1002 GARDNER DENVER air compressor. I need 2 discharge screw caps for valves, part number ACC-11. It’s stopping me from running it. I got everything else rebuilt or in check. Anyone help? I really would appreciate it.

Sounds like something you could make or have made, but I have not been able to locate an image, much less the part, so don’t know.
Sorry, but good luck…
