[filmscanners] Re: Canned air...



Moisture content in the line can be a problem when using air-compressors in a 
humid
environment.  Without a very efficient moisture collector they will frequently 
spit droplets
of water.  I have had constant problems with this problem when using an 
airbrush.  There are
ways to eliminate 95% of the moisture content but the ways I know require 
extensive
modifications to the compressor system.
