You know one thing I never figured out.

Before I traded my 92 chevy pickup in I had a $700 train horn on it (don't ask.. I've grown up since then). Was rated 152dB at 5 feet.

I used a oiless Thomas compressor with a PTFE coated piston and a 3 gallon tank. Every time I went to drain water from the tank it was ALWAYS bone dry.

The horn pulled air from around 4 inches from the bottom of the tank as it was a cylinder. The drain was on the bottom of the tank. Only thing I ever assumed was the water was being sucked out of the tank by the horn some how.


I ran it at 145psi but doubt that matters.
