3A Molecular Sieve is a highly selective potassium-based aluminosilicate desiccant designed for efficient moisture removal from liquids and gases while preventing the adsorption of larger molecules. With a nominal pore size of 3 angstroms, it selectively adsorbs water while excluding oxygen, nitrogen, carbon dioxide, hydrocarbons, and most solvents, making it ideal for applications where product integrity must be preserved.

This material offers fast adsorption kinetics, high mechanical strength, and excellent regeneration performance, providing long service life across repeated drying cycles. Supplied in 8×12 mesh, 3A Molecular Sieve delivers a low pressure drop and uniform flow characteristics suitable for both static and dynamic drying systems.

Key Features

• Selective water adsorption only due to 3Å pore size

• Prevents adsorption of hydrocarbons, refrigerants, and solvents

• High crushing strength and low dust formation

• Excellent regeneration capability and long service life

• Supplied in 8×12 mesh for optimal flow and contact efficiency

Typical Applications

• Refrigerant drying without adsorption or loss of refrigerant

• Moisture removal in PU plastics and paint systems

• Natural gas drying where selective water removal is required

• Drying of cracked gas streams

• Static drying of insulating glass units, both air-filled and gas-filled

• Dehydration of highly polar compounds, such as methanol and ethanol

• Dehydration of unsaturated hydrocarbons (e.g. ethylene, propylene, butadiene)

• Moisture removal in pharmaceutical and chemical processes

• Drying of liquid and gas streams where product integrity must be maintained
