those dryers are not necessary if you plumb correctly. both my shop and home shop use black pipe. out of the compressor it goes to my max height avail then criss-crosses coming down the wall (angled slightly to drain down) which makes like a radiator to cool the air. at the bottom there is a large drum drip (9"x12" black pipe with drain), into the building and up with another drum drip (2") then angle up or down as nec to remaining outlets. each with a drum drip. at the shop i use reg/dryer followed by dessicant for the paint booth. at the house i use reg/dryer followed by a "motorguard m-60". i rarely even get water at the inside drum drips and i am in sunny, humid central florida
