Arrow D10-04 Silica Gel Desiccant Color-Change Beads are housed in a 1/2" NPT Arrow desiccant dryer with a metal bowl and a 1-quart desiccant capacity. The beads are color-indicating silica gel that changes from blue to pink when saturated, giving a clear visual signal for replacement or regeneration. It lowers the dew point of compressed air to about -40°F, helping keep downstream equipment dry in industrial pneumatic systems. A sight-glass feature provides quick saturation monitoring, and the unit is suitable for point-of-use applications such as paint spray guns and small air tools.
