Pro Advantage 1/2" Desiccant Drying System – 1.5 Quart, 6-Stage Spin-On Cartridge, 40 SCFM, 250 PSI Max, Regulator, Shut-Off Valve, and Metal Bowl Filter

The Arrow Pneumatics Pro Advantage 1/2"" Desiccant Drying System – 1.5 Quart is a fully integrated air treatment solution that delivers clean, dry, and precisely regulated compressed air for professional-grade applications. Built to handle 40 SCFM and withstand up to 250 PSI, this unit is ideal for paint booths, auto body shops, CNC workstations, and industrial environments. At the heart of the system is a 6-stage spin-on desiccant cartridge with 1.5 quarts of color-indicating silica gel. When the beads turn from blue to pink, it's time to replace—no tools or guesswork required. The cartridge also includes activated charcoal and coalescing media, eliminating oil aerosols and vapors without the need for an external filter. Upstream, a 5-micron particulate and water filter with a metal bowl, sight glass, and overnight drain removes bulk liquids and debris. Downstream, a self-relieving pressure regulator with a 3-position locking knob provides stable, adjustable pressure with tamper-resistant control. Whether you're laying down a flawless paint job or protecting precision air tools, the D40 SCFM Pro Advantage system offers superior performance in one compact, serviceable package.
