Arrow Pneumatic 34189Q Silica Gel Desiccant Beads

Arrow Pneumatics 1-quart replacement silica gel desiccant beads (part number 34189) are color-indicating beads designed to remove moisture from compressed air in Arrow desiccant drying systems. This product is sold as a 6-pack of 1-quart jars, with each jar containing silica gel beads that visually indicate saturation through a color change, helping you know when regeneration or replacement is needed. The desiccant lowers the dew point of your compressed air to -40°F (-40°C), providing drier air downstream to protect pneumatic tools, painting equipment, and other air-powered devices from moisture-related corrosion and performance issues. The beads are reusable, enabling regeneration by heating to release the absorbed moisture for repeated use in compatible Arrow air-dryer setups. Ideal for maintenance of clean, dry compressed air in a variety of industrial and workshop applications, these beads offer a compact, readily replaceable moisture-control solution that integrates with Arrow Pneumatics' desiccant dryers and accessories.
