what,s up everone. Long time reader first time posting in this section of the forms Just bought my new air brush friday, badger 360. This is the one that can be used as a gravity or bottom feed. Went to use it for the first time today and when I went to spray I had bubbles in my cup. thought the paint was to thick (tamiya) so I thinned it some more & the samething happend again, thinned it a little more, samething bubbles . The pressure on my compressor is set between 20&30 psi. The nozzle is on tight as it will go. Hope you guys can help me/ hope I didn't buy a bad airbrush .

Bubbles in the paint usually means air pressure is leaking back into the paint feed tube. Not a good thing.

I have been using a Badger 150 for years. I usually run 10 to 20 psi. You could try turning down the air pressure.

You might want to tighten all the parts, or take it apart and look at any and all gaskets, seals, threads, etc.

Good luck. Hope this works. Airbrushing is a blast.

This does indicate that there is a problem in the nozzle of the airbrush as this is one of my methods called backflushing in the cleaning of my brush.
To do this you fill the cup with some cleaner, you block block the front with a tissue or cloth and gentle press down on the trigger to get some airflow, this air then backflushes the airbrush cleaning the paint passages. so if you do the following it may well cure your problem or as your brush is new it might indicate a fault in manufacture.

Examine the nozzle cap and paint nozzle. First, clean any paint that has solidified inside the nozzle cap.Next,remove paint nozzle and be sure that there is no evidence of dry paint. Wash out if solidified paint is found, very gently using a rolled up corner of some absorbant kitchen roll diped in solvent. Often bad seating of the nozzle or nozzle cap is the cause of problems this, check tat each step that everything is properly seated, replace the nozzle carefully and gently, checking that any seals that are indicated in the parts guide are in place and servicable. Replace in this order : paint nozzle, nozzle cap, needle. using some water, try spraying. If you cannot cure the issue consult with a the supplier/manufacturer and either get it replaced or repaired
It is important to work gently and carefully at all times when doing this as it is east to damage the needle tip or paint nozzle.

Hopefully these steps and explanation are understandable as I am short on time this morning.

Hi Tim. I have to agree with both posts above .. seems to be a leak in the nozzle area or build up of dried paint in the channels. Just take everything apart, wash them well with alcohol ... use pipe cleaners dipped in alcohol to get to the inside of the brush and some very thin wire for nozzle. Re-assemble and take care placing the seals on without twisting them and making sure they are on the right position. A missplaced or damaged seal can cause the same problem.

Quoted Text

The nozzle is on tight as it will go.


The one time I had to get replacement parts was because of this .... the small threads are easily damaged ... so dont go as tight as it goes .. but tighten with a light grip between finger and thumb... and when your fingers slide ... its tight enough ... dont use a tool!

After cleaning it again for the third time tuseday I still had the same problem, so l went back to the store & they took it apart & find a small crack in the nozel & said it was a manufacturer defect. They said I could exchange but had nomore of the badger 360. So I took the iwata eclipse hp-sbs & lets just say i'm very happy . Thanxs again.
