I have access to a large air compressor and I want to paint a vehicle. I live in a very muggy area. How can I keep the water out of my hose and gun? Or at least very little of it. I'll be draining the tank first. I'm looking at a regulator with a water trap.
You will need to build a water trap. I'm having the same problem. Lots of solutions on YouTube, or do a google search. I saw one guy had put water traps from the compressor to the tank, I might look into that.
It depends on the complete story here. A couple things come to mind, first, is this a one time deal? As in its in a buddy's shop and he's going to let you use it this one time? Two, how far away is the compressor from where you'll actually be doing the painting ? OK, let's ***ume a one time thing. Then I'd go with a cheaper regulator and water trap and put it at a point where I'm plugging the actual air hose I'm painting with. Example- there is a hose wall plug in where your painting, I'd put the regulator/trap right there then run a new air hose just long enough to do the job. You can pick one up at harbor freight cheap, I think 18 bucks for a 25 ft one. If the compressor is really close to where your painting, I'd run the regulator/trap straight off of the tank and new air hose from that. Eliminating the rest of the system to keep out any chance of contamination out of the equation as much as I could. But in either case I'd also run a small desiccant filter at the base of the gun. You can buy small ones cheap for 1 time usage that screw into the spray gun and the air hose into that. With the desiccant filter, some change colors when wet and the filter is a clear color so you can change them out as you paint and they become water logged. This way you can prevent any water from reaching the gun and causing paint surface problems... ...
