Badger Patriot 105 problem!

[Hampshirehog222]

Hi all, I have a Badger Patriot 105 airbrush which I use mainly acrylics through. Recently, I have been getting paint or cleaner blowing back through the trigger. At first I thought it was a blockage but now it happens after every use. Ive removed the moisture trap and cleaned the brush thoroughly but I'm not really sure why this happening. Any ideas?

Regards

I'm not familiar with Badger airbrushes but all the ones I've used have a rubber, nylon or teflon O-ring seal between the paint channel and the trigger. My first guess would be that seal has failed? Does it blow back through the trigger all the time or only when the needle cap is intentionally blocked to force blowback into the cup?

It appears to be most of the time. I had Surgery recently so for obvious reasons I didn't use it for at least two months. Now I'm back using it again and this keeps happening.

OK, I'm afraid you've got me then! I don't know enough about airbrushes to work out how paint / thinners can make it from the paint chamber into the trigger section without creating back pressure by blocking the needle cap. I still think that O-ring around the needle at the back of the paint chamber might be gone, but I can't explain how air pressure is pushing or pulling the paint through there, and it would seem logical that it has one fault causing the issue, not two separate ones. Unless maybe somehow in the time it's been dormant a whole bunch of seals have perished. Does it bubble in the cup as well?

Intially yes. Strip it down. Clean it out. Put it back together again. It then sprays ok for 10/15 minutes and the problem starts again......

Is the paint contaminated?

 

In any event, I recommend the troubleshooting page of Don's Airbrush Tips. He also has a review of the Badger Patriot that my be useful.

Sorry for the late reply. Don's airbrush tips identified the problem. Bought a new needle bearing seal fitted it and, Hazzah! Problem solved. Many thanks for all your help guys.
