Well then...
Posted by DoogsATX on Friday, November 4, 2011 9:28 AM

Over the summer, I had repeated issues with paint dusting coming out of the airbrush. The only paint that seemed (mostly) immune was Model Master enamel, but Tamiya became almost unusable.

I'd assumed it had to do with the ridiculous heat Austin suffered through all summer, but maybe not...

We moved last week, and I've been spending nights unpacking and (slowly) getting the garage back in order and Bench Mk.II set up. 

The other night I went to move my big shop compessor (20 gallon tank) and heard sloshing.

I've always been very disciplined in draining the compressor, just in case, and every night I'd get a few drips but nothing major. But then...I never moved it.

Turns out the drain plug was clogged, and there was probably a good half gallon of really nasty, corroded sludge water in it.

Yummy.

That sounds like another good reason to junk that noise tools compressor and go with a nice airbrush compressor.

That is what eventually rots the bottom of the tank out.

Glad you found the problem.

Keilau, I wouldn't discount all shop compressors. A good one will power the airbrush and air up the vehicle tires and allow you to run an impact gun to rotate your tires faster. If I could only own one compressor in the entire house that is what I would have as I use a compressor for more than just powering my Badger's. Wink

Wow. Interesting. It's nice to finally figure out a baffling problem, isn't it? Reminds me, I should check/drain my moisture trap more often...

Much worse with enamels. The reason he hasn't noticed before was that the acrylics are a lot less affected by the condensed water.

Better an airbrush in the hand, than ten in the car....Stick out tongue

Hmm.. bit odd, then, as he had no problem spraying enamels while having endless difficulty with acryls.  You're right, though... I'd think adding some water to enamels out the tip would tend to muck them up.

It's not a given, though, that any of that water was making it out the airbrush.  Pressurizing the air in the tank causes the condensation, else it'd stay in the air. 

I'd definitely pressure test the tank if you're going to keep using it.  Having it fail at 100 PSI (or whatever pressure the compressor automatically stops at) would tend to make things... interesting... for a very short period of time.  Big Smile

In addition to my Paashce DA400 compressor for airbrush, I have a Sears oil lub 1-hp compressor in the garage. Yes, the Sears comes in handy when I sprayed paint my cedar deck this summer. Good for small nail gun and topping off the tires too, but not much else. If I want to drive an impact wrench or any typical air tools, I will need a much bigger compressor. A 4-way lug wrench will be a more reasonable investment for mounting tires. Huh?

I run a 1/2" drive impact gun long enough to get the lug nuts off with my Sears oil less 1-1/2 hp 12 gallon tank compressor. Don't need anything bigger unless you are working on a real stubborn bolt.

I wanted a portable tools compressor to work on small jobs around the house. A "Sears oil less 1-1/2 hp 12 gallon tank compressor" will be too noisy and heavy to meet my need. My point is that there is no one size fits all tool in compressor.
