Air Brushing - Compressor Water Vapor

So, I got my wife (and me) one of the Vevor airbrush kits (the compressor with 3 airbrushes, Amazon.com). I’ve been working on setting up the airbrush in a 2ndary room with a compact paint booth filter hood, but I’m getting a lot of water vapor sputter, and as you can imagine, that leaves sub-optimal painting results.

These kits have a particulate filter on the compressor outlet, but that is obviously not doing the trick. A lot of vapor builds up inside, but still makes it through the line to the airbrush. They use 1/8 BSP oring fittings (oring in the bottom of the female, typically) on the outlet of the filter, but that can be converted over to 1/8 npt or 1/4 I spose.

Does anyone have any knowledge of a “desktop” (ie small) water filter / desiccant setup for this small of a compressor? It only runs 40 or so PSI and cycles to maintain line pressure with no tank. Heck, a small radiator / intercooler rig might work as well, with say a 12v 120mm PC fan with a water trap and then desiccant setup right after, plumbed with another airbrush hose?

Inline desiccant trap.

Steal the motoguard filter assy off your plasma?

They sell small inline desiccant filters for paint guns. I’m sure one of those could be adapted to work.

There’s something strangely unappealing about trying to make this little compressor pump enough air through filters meant for 1/2" plumbing…

Yea, I’ve seen them, but I’d like a little more volume of desiccant and another water trap before that. It’s like full drops of water are condensing in the delivery line.

Think of it more like a 1qt air tank. :nerd_face:

I use a 0.5 Gallon air tank (Amazon Amazon.com) hanging on my shop wall, both as a ‘water condensor’ and as a buffer to filter the pulsating pressure from my compressor. Air is teed in at the bottom with an additional ball valve to drain the tank and the air line to the air brush is tapped into the top. Fittings are 1/4" FPT for the tank so hopefully not TOO unappealing for you… :roll_eyes:

Oh, don’t rolleyes… wasn’t the size of the fittings, moreso the volume within all the “shop” air filter units that I don’t want to have to wait to pressurize.

Got a picture of the plumbing?

I’ll see what I can dig up… It’s not much more than I described…
Here ya go…


Air supplied via quick connect, through regulator, teed into bottom of tank where there is a drain with a shutoff valve. Air Pressure Gauge teed with shutoff to Air Brush hose. Not tricky and it takes care of any water from my very old, sloppy, air compressor running in a very wet garage.

Thanks broski. I got that tank on order.

Now to fabricobble a stand together for it so I can put it on a table top
