Dave ,
I don't know anything about drying the media but I do know a little about
compressors and compressed air .
Compressed air is 100% saturated when it exits the compressor and water
vapor will condense all along the air lines as it cools .This is where a
separator
will eliminate the droplets but not the remaining vapor , which will continue
condensing as the temperature falls right to the blaster nozzle which is
usually
the coldest point (below ambient temp) due to the sudden expansion of the
compressed air .
The normal $$$ solution is to use a refrigerated dryer with separator which
cools the compressed air to about 2 degrees C .
When I need dry air ( not very often ) I coil up 2 or 3 metres of airline into
a
bucket containing a mixture of water and ice and fit a separator after the
"cooler" . This system works well until the ice melts !!
