4A 4x8 Blue Indicating Molecular Sieve Desiccant Visual Moisture Indicator for Industrial Drying

Product Overview

4A 4x8 Blue Indicating Molecular Sieve Desiccant by Delta Adsorbents is a sodium aluminosilicate molecular sieve impregnated with an inorganic metal salt moisture indicator. This desiccant performs as a standard 4A molecular sieve with the added benefit of visually indicating saturation levels. When active, the beads are blue; as they reach saturation, the color changes to beige, signaling the need for replacement.

Key Features

• Visual color change from blue to beige upon saturation
• 4Å pore size for selective adsorption of water molecules
• High adsorption capacity and mechanical strength
• Suitable for various industrial drying applications
• Available in multiple packaging sizes

Typical Applications

• Natural Gas Drying: Efficient removal of moisture from natural gas streams
