How Important is that Moisture Trap?

I think that moister trap is essantial for an airbrush. I bought a Pache moister trap from a hobby store and it's great. It shure is cheaper and better than the ones that come atached to the compressor. In a few months I get 1/4oz of water. So I strongly suggest for everyone who has a compressor to get a moister trapper.

I agree. At less than $20, it's cheap assurance no moisture will ruin things.

Both Darrin and Berny have nailed this one ...... for the little extra cost, buy the moisture trap. It'll save you a lot a pain in the end.

It is very important. Air is drawn into a compressor from an outside source. As it compresses the air it heats up. As the air travels along the supply hose it will cool down where the moisture condenses and forms drops. When it passes through the air brush, it can spoil your paint job, by spraying water all over your subject. I live in NW Florida and even in an air conditioned house, in the summer my moisture trap requires frequent draining. In the winter when it is less humid, it will still fill up.

I have heard that a tank filled with dry nitrogen will not cause condensation.

The moisture trap can be crucial, especially in humid environments. It basically keeps extra moisture out of the air flow, which can lead to eratic spray patterns, paint too thin, bubbles in the paint, or even corrosion of the gun. If in doubt, get one. It's worth the extra bucks just for a little insurance.
