problem with water in line, messing up paint when spraying..
anyone have advice w/a problem with water buildup in the compressor lines?
have already installed a refrigerant air dryer and multiple dessicant filters before hitting the booth. the refrigerant dryer and dessicant filters are working since there is lots of water being trapped. but water manages to get through the lines and to the spray. so here are questions;
1. should the compressor and refrigerant dryer be located as close to the booth as possible and should the booth be the first compressor hookup outlet line, then tools or whatever else after the booth or does it not matter? what is your setup look like?
right now, the booth is setup to be the last item from the compressor and all the tools hooked up between them.
2. can the compressor be the problem by creating high water condensation? notice the compressor is constantly cycling on a 60 galllon tank from multiple users tapping in on it which could cause more condensation from heat build up or is this not a problem?
3. someone suggested the refrigerant dryer should be kept on at all times and not turned off to not allow any water to buildup or residue in the pipes over night or during the time it is not being used. does anyone else do the same?
appreciate any advice in this regards.
Sounds like you are asking too much from your compressor. A 60 gallon is generally considered the smallest size for home/garage use and painting... and this is with the right spray gun that is not an air hog (like the Plus and others).
If you are using the compressor in a shop environment with multiple users, it sounds like you need to step up to an appropriate size compressor for what you are trying to accomplish.
I agree with George
You should be using an 80 gallon (or larger) compressor that puts out enough air for your shop. If the compressor that you're using is working too hard it will tend to heat the air and generate moisture that can be difficult to control.
Copper or steel lines with a couple vertical drops is going to go a long way towards condensing out and capturing most of that water you have there. TIP the outfit that makes sandblasters has a nice pictorial on thier site somewhere showing how to do it simply and cheaply. Tha'ts all I use just 3/4 copper and 2 24" J traps with water faucet drains on the bottom of them and a cheapo filter out where the hose begins. The long vertical runs will make it run right into the traps.
great advice. We had the same issues til we fixed the lines and gave the water a little obstacle course.
Here is the link to the TIP schematic. I posted it as I remembered after mentioning it in my post how hard it was to find in their site. That's about all you need in some form or another be it black pipe, or copper whatever you have cheaper on hand and works for you. This does the deed for me even on a super hot dry day where the tiny little 26 gallon 6.5 HP ( yea right) Campbell Hausfield compressor pumps it's heart out to make it around a car making water like a mother.
Actually it can be very simple, you can just pipe it from your compressor to your regulator using about 20 or more feet of 1/2" or 3/4" pipe angled so that the moisture runs back to the compressor where it can be drained from the tank. A drop at the other end that goes past the filter/regulator will supply a drain at the other end. The smaller the compressor the more water that you'll need to remove.
I have an 80 Gal, 5HP, 3 Cylinder Compressor. I added a 20 gallon tank and ran copper lines as shown in the link above. I get 0 moisture.
Other than running the lines and keeping them drained, the best thing is the extra tank, this allows a place for the air to sit and cool off.
You can keep your 60 gal, but I would add a 20 or two to your setup.
Moisture in lines
I use an 80 gallon compressor with small air dryer in line. My line runs through a wall to my sharpe membrane air dryer, best thing I coulda added. It drains oil, and water by itself (maintenance free) it was pricey but well worth it clean air to spray.
