1/2" Desiccant Filter Dryer – 1 Gallon Capacity, Color-Changing Silica, 30 SCFM, Lowers Dew Point to -40°F, Includes Desiccant
D12-04XXL
The Arrow Pneumatics D12-04XXL Desiccant Filter Dryer is the ultimate in high-capacity air drying performance for 1/2" compressed air systems. Featuring a 1-gallon desiccant capacity, this unit is built for 30 SCFM flow and delivers clean, dry air for critical applications such as paint spraying, woodworking, instrumentation, and automotive finishing.
The silica gel desiccant beads visibly change from blue to pink when saturated, providing a clear indicator for replacement. This makes system maintenance predictable and prevents downtime due to unnoticed moisture buildup. The refillable bowl design—equipped with a bottom-mounted filtration rod and secure screw collar—makes servicing fast and easy.
An integrated 40 micron sintered bronze element protects your air tools by removing fine particles and desiccant dust before they travel downstream. Designed with 1/2" NPT ports, this unit fits seamlessly into most existing air line systems.
Supplied with 1-gallon of desiccant beads, the D12-04XXL is ready to perform straight from the box, making it a go-to solution for any operation where air purity and reliability are non-negotiable.
