Aircom flat 20A is leaking oil

hello guys,

I really like to ask you for some help. I have brought a aircom flat 20A compressor secondhand. And now he is leaking oil. I found oil by the red arrows (pic 1) and on the roof of the compressor (pic 2).
Because I don't have a manual of the compressor I don't have any idea what part is causing oil leaking and how I can fix it.

I also think it is a good idea to change the oil, since i have no idea how long it's in there. But Because I have no manual, I don't know what oil (and how much) I need to put in.

I have tried to contact the factory to ask a manual, but they don't respond to my email.

Does anyone recognize this oil leak problem? And can you tell me what to do?

And my last question; is there anybody out there who also has a Aircom flat 20A and have a manual? I would really like a copy.

I hope somebody could help me out!

Greetz, Maffie

The second photo appears to be just where the oil is pooling rather than coming form that point. Where is the highest point you find the oil... find the drop and follow it upwards and that should identify the source. Maybe wipe all the oil off and see where the drips form first. It may be a poorly seated seal...

Thanks for you're help. I am cleaning him now so I can try to search the source. Is it possible that the oil is to old and not working properly and that it gets to hot and "boil" over? (I hope you understand what i mean)

Yes... it looks OK - eg not old. It could be they did an oil change and spilled some as well... Unusual there isn't a manual. I found something similar for a Jun air compressor but not sure if it's the same animal.
 
I'm with mark , Do a good cleanup (take the covers off so you can see everything) also I would change the oil because you don't know when it was last changed and that if it was changed did they use the right oil? As for the oil on the cover that might be from it getting turned upside down during shipping(leaking out the valves and running out the air inlet)
 
Thanks for you're help!
Tonight I did a clean up and a test. After ca. 3 hours of airbrushing I found a little bit of oil on the roof and a little bit in between thoose 2 things where the yellow arrow is pointing to. I also have found that the black plastic bolt (red arrow) is loose. Could that black bolt be my problem?
I already have emaild the airbrush store for oil recommendation ( to be sure I buy the good one).
Who can tell me what the function of toose bolts is? The hold a black thread.

I think the unit with the black screws is the pressure control switch...

Did you snug up the plastic nut?that might be your leaks? its a pressure switch and needs the air pressure in the tank to turn it on and off you might also have oil in your air tank?Have you drained it to see if its got oil/water in it?also can you remove the black cover over the switch?might just be a loose pressure fitting
 
It might be my eyes/screen but that knob (red arrow) looks to be possibly cross threaded ?

Hoi Maffie

When you take delivery of a new fridge and it has been moved around a lot during the delivery process, they always recommend you don't switch it on for 24 hours after you put it in its place, the reason for this is the oil that should remain in the the bottom of the fridge motor gets bounced around and mixes with the coolant in the fridges pipes causing it to not work properly and even cause damage, these silent compressors use the same type of fridge motors and the same rules apply, so I'm guessing there is nothing wrong with your compressor except that you started using it as soon as it arrived:) because of this you unwittingly have the bounced around oil all through your pipes, your only solution is to have your pipes cleaned and I would guess, your tank too, if you know anybody who is a bit mechanical let them do it for but you won't get the best out of the compressor until this happens.

Any manual for the same type of compressor (20A) will help you, the only difference is the shape of the tank and maybe where everything sits but the parts and what they do are more or less the same.

And the two black plastic nuts are only cable guides, they are only there to stop the pipes or cables being damaged.
 
Hi maffie,
Yes I have an Aircom Flat 20A compressor and mine leaks in exactly the same place. I just wipe it off and I've put a little plactic pot underneath those bolts to catch any drips. It's no big deal as far as I can see and it hasn't effected the performance of the compressor. The oil drips from normal bolts underneath those Black Cable Guide Bolt Things.

I bought my compressor from Lion-Art in Holland and I get my compressor oil from him (scroll down this page link for the Oil) http://www.lion-art.nl/contents/en-uk/d44.html

To drain the Oil you have to unscrew the Oil Level window once you take the casing off but I've not done that yet, I was told to change it every 3-5 years depending on usage. I presume you need to put something directly underneath it because if you can see oil through the window I would think it would start leaking out as soon as you begin turning a spanner.

I have scanned the Manual in English for you (no Dutch version) but it doesn't give much information.

If you have any more questions just ask. I hope this helps.

You are right! Today I have got contact with a airbrush/compressor repair service, and he told me that it is a "pressostaat". My good friend Google Translate tells me that in english they call it a pressure switch.

Sorry, I don't understand what mean. (My english is not so great, especially "technical terms")

I have this compressor 2 months now. And he seems to be okey first. But suddenly I found some oil-water mix in the filter. I cleaned it up but it came back. Then I take a better look and find the oil spots from the photos.
 
I have contact an airbrush/compressor repair service and he told me this: (The words with a * behind are the words google translate give me.)

From the photos I'll send him (the same as in this topic) he could tell me that I not regular blow the dust away that is on the compressor and that it is possible that the airfilter is constipated* whereby* a underpressure* *arises. Because of this oil can get in the pressostaat/presure switch. He told me to unscrew it and clean it with break cleaner*. And also clean the pressure regulator* the same way and add a little vaseline on the rubber rings.
And he told me that if I want to switch the oil I need to take "Sitcom oil" and nothing else.

Also Aircom stops 1,5 year ago with the production of compressors. Most parts can be replaced with parts from the brand "Werther".
I wanted to replace the airfilter to be sure it is okey, and he told me that is is better to replace it with a airfilter of Werther. With a 1/8-1/8 reducer* (I mean some bolt or screw). This filter is better and easyer to clean.


(Because of all the technical terms I don't know I'll put his words in Dutch here, maybe some other Dutch person can translate it better in "airbrush language": Aan je foto te zien is hij niet regelmatig afgeblazen of zat het luchtfilter verstopt waardoor er onderdruk in het motortje is ontstaan en de olie in de pressostaat terecht gekomen is. Even uit elkaar halen en met een bus remreiniger schoonmaken. Zelfde geld voor de drukregelaar.)
 
Okey, now I am gonna try to do this! I have brought some breakcleaner. But I looked to the compressor I now I am thinking..can I really unscrew the whole pressostaat?? I'm a bit confused now. But I think its the best to just start and look how far I can come.

"Looking at the photo it seems that it is not regularly dusted off or the air filter is blocked causing under pressure in the motor allowing oil to enter the pressure cut off switch, take it apart and clean it with (spray can) brake cleaning fluid, this also applies to the pressure regulator."


If you are not sure how to do this let someone else do it, it's worth paying a little to have it done, it's not that complicated a job but could be more expensive if you mess up.
