drying air from a compressor

["Mordecai Dunst"<mdunst@smtplink.coh.org>]

     I seem to recall this topic was discussed previously BUT, 
     
     What is a simple yet effective way of drying the air from a compressor
     running in a mildy humid enviroment.  The compressor is a 5hp sears 
     with a 30 gal tank.  It will be run "hard".  For a "sand blaster" type 
     set-up.
     
     Thanks in advance for any reasonable suggestions. I have a "filter" 
     water trap but the volume of air it pushes exceeds the capacity of the 
     water trap.  Should I gang-up two or more traps?
