Historybuff Posted October 28, 2020 Share Posted October 28, 2020 Hey, guys! I have a question for you guys. I have a Master TC-40T compressor with moister trap. In my last clear coat session, I noticed something that hasn’t happened to me before. My siphon fed external mix Paasche H airbrush is spitting what appears to be water when I use just the air to help the clear coat dry faster. I close the tip of the airbrush to keep anything from coming out of it but air, yet it still seems to want to periodically spit water (I think) when nothing should be coming out but air. I’m wondering if it’s possible my water trap connected to my compressor isn’t catching all of the condensation. Has anyone had this problem? Would it be a good idea to get an additional water trap to fit on the airbrush itself as well? Just FYI, I have a Paasche hose and airbrush; however, everything is fitted to Iwata size connections to allow me to interchange airbrushes without switching the hose or anything out. So I’m assuming it would be best to get an Iwata moister trap for the airbrush if that is the problem? Thank you guys ahead of time for any responses to the issue. Oh, and a little bit more information about it spitting water. It seemed to start closer to the end of one of my clear coating sessions. So I’m wondering if it may have just got a bit too hot and the air condensed inside the hose after passing the water trap on the compressor. Quote Link to post Share on other sites
Bob Beary Posted October 28, 2020 Share Posted October 28, 2020 Is there visible water in the moisture trap on the compressor? Have you drained that? When was the last time you drained the tank? Bob Quote Link to post Share on other sites

Tbh, I have only used this compressor maybe 4-5 times for about 30 minutes. I haven’t drained it yet. I feel kinda stupid now. Lol. It’s still pretty new ,and the guide was less than helpful.

Historybuff Posted October 29, 2020 Author Share Posted October 29, 2020 11 hours ago, Bob Beary said: When was the last time you drained the tank? @Bob BearyI just opened up the tank to let any water out. None to speak of in the tank itself. Just a tiny bit of water in the moisture trap that I can’t seem to get out. Quote Link to post Share on other sites
Bob Beary Posted October 29, 2020 Share Posted October 29, 2020 You should be able to push up on the fitting at the bottom of the moisture trap to drain it Possibly the trap ca be unscrewed. I drain my compressor after every use. Bob Quote Link to post Share on other sites
ElectroSoldier Posted October 29, 2020 Share Posted October 29, 2020 My first port of call would be a minor service of the air compressor... Drain the air off the tank Vent the tank to atmosphere Remove the drain plug and drain anything from the tank Replace the plug Clean out the moisture trap Quote Link to post Share on other sites

I have looked at this moisture trap. I’m having trouble figuring out how to take this one apart to clean. I’m going to keep trying. Just not having luck figuring this out. There is zero information online that I can find about this particular type of moisture trap. If worse comes to worse, I can call the company to ask. Quote Link to post Share on other sites
ElectroSoldier Posted October 29, 2020 Share Posted October 29, 2020 You dont need to take the moisture trap apart, in fact you shouldnt take it apart at all. There is a dump valve on it to empty it out, that is all you should need to do. If you have removed the drain plug on the tank and emptied it out then Im not sure what is going wrong. Maybe leave it off for a day or two to make sure any water in there is gone... If the compressor tank is completely free of any water and the moisture trap has no water in it and it is working properly then the water might be creeping in in the air line between the moisture trap and the airbrush. How long is the airline from the moisture trap to the airbrush? Quote Link to post Share on other sites
Bob Beary Posted October 29, 2020 Share Posted October 29, 2020 One more thing to try...run the compressor with the air line (hose) attached, but without the airbrush. Just let it run for a few minutes to blow any moisture out of the line. Hold the end of the hose to see if any water comes out. Bob Quote Link to post Share on other sites
Historybuff Posted October 29, 2020 Author Share Posted October 29, 2020 Update: I did take off the moisture trap and was able to get most of the water out of the trap. I then ran the compressor as @Bob Beary suggested. No more water seems to be coming out. I’m thinking that solved it. I still plan on calling the company to see how if they can tell me if and/or how to take this particular moisture trap a part to clean. Quote Link to post Share on other sites
Night Owl Models Posted November 7, 2020 Share Posted November 7, 2020 Alot of interesting comments. I had this exact problem and here is your solution a Paasche in line moisture trap it works like a dream. I live on the west coast rain forest belt super high humidity I solved some of my issues by switching from enamel to acrylic. It matters because if moisture makes it into your brush the atomized moisturs can be absorbed by acrylic paint. Additionally the inline moisture trap gives you a hint when it is overloaded by releasing a little spit through a set screw on the side. When that happens I just open up the set screw and let the moisture blow out. Best of luck hope this helps. Quote Link to post Share on other sites
