For sale is a INGERSOLL RAND DS15 DRYSTAR 38DA COMPRESSED REFRIGERATED AIR DRYER. I tested both units by plugging them in. I observed that the indicator steadily moved from red to just between green and blue. I interpret this as a sign that it is working fine. These units were made in 2007 and 2008, which makes them relatively recent. They can be hung on a wall, they have holes to be hanged or you can just stand them on whatever you want. You should install a filter in front of this dryer. R-134a refrigerant. Military surplus. One dryer per bid.
