DeVILBISS DAD-1 Silica Gel Desiccant Beads Equivalent – 55 lb Bag

2–5 mm blue indicating silica gel beads provide an aftermarket alternative to DeVILBISS DAD-1 desiccant for compatible compressed air drying equipment. Supplied in a 55 lb bulk bag, the beads change from blue when dry to pink as they adsorb moisture.

How It Works

The porous silica gel beads adsorb water vapor as compressed air passes through the desiccant bed. A cobalt chloride indicator changes from blue to pink as the beads take on moisture, helping you monitor when the media may need regeneration or replacement.

Features & Benefits

• Aftermarket alternative to DeVILBISS DAD-1 desiccant
• 2–5 mm blue indicating silica gel beads

Common Uses

For refilling compatible compressed air desiccant dryers that use DeVILBISS DAD-1 or equivalent blue indicating silica gel. Suitable applications include point-of-use air drying for painting, finishing, and other processes requiring moisture-controlled compressed air.

Installation & Maintenance

Shut off and fully depressurize the dryer before servicing. Confirm the required media type, bead size, and fill quantity, then follow the equipment manufacturer’s refill instructions. This 55 lb bag is a bulk supply; use only the amount required for your dryer.

Maintain upstream filters and drains to keep liquid water and oil from reaching the desiccant. Keep unused beads tightly sealed, and monitor the color indicator alongside dryer performance. Follow the supplier’s instructions if regenerating the media.

Handling Precautions

Contains cobalt chloride. Do not use in direct contact with food, pharmaceuticals, or other products intended for consumption. Follow the product Safety Data Sheet for handling, protective equipment, and disposal.

Why Choose This DAD-1 Equivalent?

This bulk desiccant provides a practical aftermarket refill option for equipment using DAD-1 equivalent media. The blue-to-pink indicator helps you monitor moisture loading, while the 55 lb bag lets you keep replacement beads available for scheduled maintenance.
