Airbrush spitting problem

Hi

I am having a problem of having the airbrush spit water every once in a while. the system I am using is a Paasche single action airbrush and a Central Pneumatic compressor model #95630 with water trap. If there was water in the line I would expect to see the trap fogging up but I do not see this happening? What can be done to prevent this from happening?

You need another water trap, mounted inline and near the end of the hose on the airbrush side. The compressed air is warmer and condenses, humidity makes it worse. Paasche makes a moisture filter that you can splice into the hose. Oddly their hoses that come with a filter mount it far too close to the middle; it's best to buy a trap separately and splice it into the hose very close to the airbrush end, not the middle, and not close to the compressor outlet.

I had the same problem, aswell as the water trap on the compressor itself, a water trap in between the airbrush and the hose is also required. Since fitting the "in-line" trap, the airbrush spitting problem has ceased.

You can get them off eBay for next to nothing.

Or put the hose in a cold bucket of water. Cool air = less water in the air.

If the hose is long enough, try keeping a loop or two inside the cold water before the airbrush. Might sound crazy but it works. Also scaleauto mag did a tutorial a while back, maybe bob can help us. Or search scaleautomag.com

Although there is probably more than one way to solve your problem, you should save yourself a lot of headaches and listen to Zoom Zoom and Indy. I had the same problem and purchased an in line filter. I've never had a moisture problem since. Zoom Zoom probably offered the same advice to me when I posted my moisture problem last year.
