Mayday Mayday - Sudden Airbrushing Problems :(

[Guest]

Yes, too unusual for the same thing to happen to both brushes at once.

Just thinking out loud but since an airbrush works on the venturi effect, just like the spray guns I'm more familiar with, if the airflow/volume is reduced from your air supply (not necessarily pressure), then there may be just enough to pull a thin fluid like cleaner or water through, but not enough to pull the relatively thicker paint or primer. So that would put me with everyone else that thinks it's compressor, or maybe regulator/hose/connector related, where you are getting some air, but not enough.

I noticed you mentioned the compressor getting hot. If this is unusual then I would suspect it’s definitely the compressor, and would look at the potential causes of the heat.
Perhaps a blockage or an obstruction?

Hi all thanks again for the suggestions.. Its been sitting over night so will see how it is this morning.

It's an A186 compressor.

Hi Warren
Have a look at this video. Removing the head and servicing the compressor might help. I did mine. Relevant section starts about 5 mins in.

It's only a month old would it need that level of intervention

I had to strip & clean mine out after owning it a few months, been fine since.

Because so many people rebrand these I'm guessing QC is very lax, so there are good ones and bad ones out there.

Certainly shouldn't if it's that new but Andy has hit the nail on the head. They are cheap and so maybe poor quality ones slip through.

Just be careful tightening up those head bolts. I photoed mine as I took it apart, so I didn't get anything the wrong way round when reassembling.

Check the needles along their length, do it by feel and you will feel if there is any buildup that has not been cleaned away. I give mine a strip clean after every session but still miss a fraction and that causes mine to miss behave.

But would this be both brushes ?

Could very well be, if I have not used an a/b for some time and when I tried the trigger it was stiff, when stripped down I found that there was a build up of residue below the 'trigger'. Cleaned that and all was well.

Hi, just read another of your threads, am I right you changed the "precision regulator", did your problems start after this, just a thought. If so go back to as it was and try again with the airbrushes.

nope was happening without the new regulator fitted.

Have spent the day stripping brushes again, checking the compressor and all fittings. Will get a chance to test after dinner

[Bortig the Viking]

Will keep my fingers crossed buddy.

Having experience of problems with air brake and hydraulic systems I would ask how old is your air hose? Sometimes the inner can start to collapse and cause irregular pressure variations, has the hose been stood on, or severely kinked at some time?
