moisture in air tank

[full fan]

Other than  a in line water trap any other way to keep moisture down in the tank?  Tank is 13gal.,was thinking of draining & removing  the plug out till ready to use.

[Richard B]

Yes, remove plug to drain out moisture.
In line water trap does not remove moisture from tank.
Do not remove plug while tank is pressurized.

If I leave the plug out till ready to use that will help dry out the tank of the moisture?

[Richard B]

Yes.
I take my plug out everytime I get done for the day.
You can also turn the compressor on for a minute or two while the plug is out to force some of the moisture out.

Thanks Richard I will start doing that,it's got to help

Weird thing ...
I have had  my compressor indoors and situated over a floor vent (for the central heat) since about 2001. It wasn't intentional - that was just the best place for it to sit.
It took over 5 years for it to accumulate enough water in the tank to where I could even hear it slosh.
My first compressor already had that much water inside it when I first opened its box.

Taking the plug out will only take out the condensed moisture that is already in there. 

Two ways to prevent water in your lines is:

1.  Prevent the water moisture from getting in there.

2.  Trap it after it is condensed in the tank. 

Sounds like Nancy has hers in a nice dry location.  The less moisture in the air the less in your tank.  A dehumidifier in the room where you keep the compressor should help.  A line trap, moisture trap or drier is needed in most cases.

We've got big (50+HP) compressed air dryers in the plant where I work, but I don't know if there are much smaller personal use dryers that operate the same. They are much like a dehumidifier, as they cool the compress air to condense the humidity out of the air. They usually have two traps so it can switch over to "dump". It might be something to look into. Also, it would be best to install between the compressor and the tank. You want to drain your tank frequently to control rust, anyway.

There are smaller units available.

I use a moisture trap at the tank then another remote tank qith a moisture trap on the out going line to the air brush or spray gun.

Great perfectly dry air all the time.
