Air Compressor Water Trap

Any suggestions on a good online water trap that actually works? I do not have a huge budget but these Chinese versions are crap.
 
What you spraying? You could go "all out" with a sata 500 filter series; but I'm guessing that's overkill.

I'd look to the paint companies, however; I bet BC has a good water filter.

You wanting to remove the water going into the tank or coming out of the tank?
 
CT30 is a few hundred bucks, buy your desiccant from Amazon its 1/3 the cost of paint store.
It takes a cartridge full of the stuff.
I make my own cartridge with women's stretchy leggings.20230507_103037.jpg
I use to run the QC3 ahead of the
CT30 but the cartridge is really expensive to keep replacing.
If your not running a automatic tank drain remember to drain compressor daily.

I got my desiccant beads on Amazon IIRC. When they turn pink or red, indicating the need for a change, I reuse them by warming them on a big cookie sheet in the oven until they turn blue again. Seems to work well.

When ever you tee off your main line, the tee should point up then loop down to the working height. Every down leg needs a water drain. Make sure your main line is angled so it will drain and has a drain valve. That should be all you need for blow off air. For paint spraying do what Bc'z does.
This is all I did (well, my pipefitter friend did!). A bit of pipe down, a valve to drain, a glass to see if anything there.

I also have a manual tank drain. I mean, some pipe coming out the bottom, another ball valve. Blow it out every... once in a while. In anything /like/ production use rate I'd get an auto-drain and pipe outside, but they are only only for that so can blow out in a matter of hours. I don't need it that often. It was a few months after install before we did all this, and the first drain was a lot of water and rust, since then it's just pretty clean water, none in the lines, so even in humid KS just basic piping principles and occasional draining keeps it very happy.

If you have a very very damp-sensitive use case, get dryers etc. absolutely!
 
This pic is a two-fer;

The coil on the right actually isn't part of a still.... it goes around a wood furnace exhaust to pre heat water going into water heater tank. However,put a cpl QD fittings on it.... and chunk the whole thing in a 5g bucket of ice water as a hillbilly "dryer". Watch your line routing,not only on this,but ALL compressor plumbing.

The finned pieces were pulled out of an old house that was their base board hot water heat. Took out miles of the stuff. It's basically what's posted above by Aaron... just next level. The small one was made as a "remote" setup for spraying cabinets on site. The longer one was for a very specific space envelope in a friends shop. Excuse the dust(it's our shop bathroom,maid is way overdue).

I know, what you know, that we know what comes drippin off the end of that copper.....

Let's get to sippin!!
 
We use Grainger PN#6ZC63A disposable inline filter/dryers at the control valves of our plant. They work pretty well and were only about $25 for a two pack last time I purchased them. It is a combination desiccant beads and a 40 micron filter. These are too small to use on the main line coming out of the tank but work very well for point of use situations. I am also +1 for the solenoid drain valve with a timer. It takes care of a large majority of water issues with our compressed air and in combination with the point of use filters, would probably take care of what you need.
