This 1/2'' compact desiccant dryer with 1 quart capacity delivers extremely dry, compressed air as low as -30 degrees Fahrenheit. Incoming air is dispensed through a 70 micron polypropylene element for removal of particles. The air is then distributed uniformly through the desiccant to the bottom of the bowl where clean/dry air enters the intake tube. As the desiccant beads attracts water from the compressed air and become saturated, the color changes from blue to pink. Maximum pressure of 250 PSI.
