I have a double action airbrush with compressor. I keep getting water thru the airbrush while painting. It has a regulator with moisture trap the I purge regularly purge can anyone help. Please!

Mark,

You may be be developing condensation in the air hose. Install
an inline moisture trap close to the airbrush and this should
resolve the problem.

Cheers,
Joe

Mark can't agree with Joe more,excellent idea, I don't have a lot of experience with airbrush moisture problems but I have a lot of experience working with pneumatic tools such as air gun nailer's and such working in humid climates and in those cases we would put a dehumidifier close to the compressor and this would help protect our tools from excessive moisture build up. Now I've been to Oregon a few times , Lovely but wet in some areas so if you have access to a dehumidifier + the in line moisture trap that Joe is recommending it might be a winning combination. Try the in line trap first and if it doesn't solve the complete problem look for a dehumidifier used on say craig's list or something of the sort, That might just do it?

Also are you emptying the main tank along with the moisture separator if not the separator will never keep up with what is accumulated in the main tank reservoir?

Hope this helps! Just my 2 cents..

Craig..
