air lines

[rubadub]

This type of airline will do a decent job of getting moisture out of your lines without an air dryer.

Interesting. Thanks - bookmarked.

So he is sending it all the way wcross the room and back again after tapping off the top of his tank?
I guess it would dry and cool the air on a trip that long, and the slope will help in draining, but I sure would do a cost comparison before I did it that way.
Half the pipe and a cooler may be cheaper.

Its best to get at least 50 feet of pipe in before you go into the filters to let the hot air from the compressor cool to get the water out.

I found out by changing my lines around, I didn't have to buy an air dryer.

I do a little sandblasting, and kept getting moisture in my sandblaster pot, after I put in more pipe I got rid of the moisture.

I would agree that this would remove a great deal of water (I have a back-and-forth scheme on my cooler), and is quite sufficient for blasting, but if painting is a possibility, you want a real dryer.

I'm just a hobbist, but we have done a lot of painting, and we never use an air dryer.

If you can sandblast without getting moisture into the sandblaster, then you will never have it in your paint.

I guess I went through about 1100 lbs of sand a couple of months ago, and I didn't have any moisture problems.

A compressor will run continuously when your blasting, anyway mine will.

I used to have a problem with moisture, then I changed my airlines around, and finally got rid of it.

If you run short lines, or don't taper them enough, with some drains along with it, then an air dryer would be in order.

I think air dryers are a good idea, but if you run enough black pipe, you won't need it.

Well, I'm not looking to start a ******* contest, but you can't get completely dry air out of a pipe that has water in it. I blast with glass beads the size of flour (almost), and don't bother with a water separator either when doing this, but that little bit of remaining water will show up in a paint job.

A lot also depends on what part of the country you are in. Around here summers seem like 100% humidity a lot of the time. The only way I could reasonably work things was with an air dryer for blasting and the plasma cutter.

I run quite a bit of black pipe, about 60 feet before it hits the first three filters, then another probably another 40 feet into the paint booth and into another filter.

I run a large bead blaster, it goes about 60 feet after the last filter, then a rubber hose into the blaster.

I'm in Wisconsin, 30 miles south of Green Bay or 100 miles North of Milwaukee on lake michigan, and we get a few humid days, but not many, and I never have a moisture problem.

With a sharpe F-88 type filter, you can leave it alone for a year or two before you ever have to look at, but I'm not sure how an airdryer works or how much you have to do maintenance on it.

I changed out the stone filter in my paint booth one time, and thats because my air compressor let loose with some oil, and if you took it out right now it would be snow white, but I run three F-88's before it gets to that one.

Its all in what works, I'm 66 years old, and if it works, I won't touch it.

And if an airdryer is doing the job, I wouldn't touch that either.

Looks like that setup would work good, I have 45' of 1" in an "M" shape that takes about everything out before the filter. Hook that up to what I already have using all 1" & could probably take off all 4 tires with the tank valve shut off just running off the air in the pipe.
