Hello,
I have a new airbrush, a Paasche VL set. I live in a fairly moist environment and want to install a moisture trap in my airbrush hose to prevent the water from getting into my paints. Would it be better to order the 10 foot Paasche hose with a moisture trap installed from Dixie Art or just buy a moisture and install it myself on the six foot Paasche hose I have? Any advice on the pros and cons of each would be greatly appreciated.
Also, has anyone had any problems when ordering from Dixie Art? Thanks for your time.

Hey Cody. I used to work in the automobile business for several years. Most of your big shops have dryers in line with all their air compressors. But the average person couldn't afford that just for their personal shops. So you have to rely putting enough line in to avoid blow thru on the moisture that builds up from the condensation from your air tank On my shop I put air line around my walls. With moisture traps. Some use copper but you can use a PVC that is approved for air.
I used schedule 40 white,3/4 inch, but I don't think white is approved. Start from your tank. Go about 4 feet up hill, put a "T" in. Now run a piece of pipe about 3 to four feet down towards the ground put a shut off valve here. Staring back at the top of the "T" Run your line again up hill away from you air tank. Ten foot later put another "T" in and repeat what you did on the first "T" a line going towards the ground and another shut off valve. Put about 4 more feet around then plumb it so it will accept your standard air hose. Now at the pipes that run towards the ground make sure you glue shut off valves at the bottom . (this is for draining you air lines) What you would have built would be line traps. You would not believe how much water it would catch. Also I would put a factory built moisture trap at the begriming of your spray gun air hose. Also where you start you will have to plumb with the fittings that your air compressor uses and to when I said uphill.... what you are trying to do is make sure the water will be going back towards the trap or tank instead of your spray gun .. My air pressure is about 180 pounds I have used a lot of air tools for spraying you don't need near as much. Also make sure you fasten the pipe to the walls so their will be no movement on the joints.. Hope this helps Randy C
Since the air coming out off the compresser is quite hot around 180degrees F. build your self an expansion chamber in line to cool the air. To do this you can use pressure rated PVC 4" pipe in a 3 foot length or so. Have the air enter the tube in the bottom and exit out the top. Fill the tube with bronze wool to provide the water more surface area to condense on. Be sure to install a drain valve in the bottom. When the hot air expands it cools which causes the water to condense out. The other method would be to take a small refrigerator and run tubing coils inside bringing the air temperature down, install a "P" trap sump in line to drain the water from.
