Product Overview

What Is 4A Molecular Sieve?

4A molecular sieve is a sodium-type zeolite adsorbent with an effective pore opening of approximately 4 angstroms. It is widely used for drying gases and liquids where water and other small polar molecules need to be adsorbed. Buyers comparing the full product family can also review the Molecular Sieves parent page.

Compared with ordinary desiccants, molecular sieves can provide deeper dehydration under suitable operating and regeneration conditions. 4A molecular sieve is commonly reviewed for compressed air drying, gas dehydration, liquid drying and selected purification processes. For dryer-media comparison, see our Activated Alumina vs Molecular Sieve guide.

The correct 4A molecular sieve grade depends on the process medium, target outlet moisture, particle form, regeneration condition and equipment design. A grade name alone is not enough for final procurement confirmation.

Grade Comparison

4A Molecular Sieve vs 3A, 5A and 13X

Molecular sieve grade selection should be based on the molecule to be adsorbed, pore-size requirement, process medium, operating conditions and regeneration method.

Grade Typical Direction
3A Molecular Sieve Selective water adsorption where larger molecules should be excluded from the adsorption system.
4A Molecular Sieve General gas and liquid drying, compressed air dehydration and selected industrial purification applications.
5A Molecular Sieve Separation and purification involving selected gas molecules, normal paraffins and process streams.
13X Molecular Sieve Larger-pore gas purification, carbon dioxide removal, dehydration and air pre-purification.
Selection note: The same molecular sieve grade name may have different particle sizes, bulk density, crush strength and adsorption data from different manufacturers. Final selection should be based on the confirmed TDS, COA and application conditions. For a broader pore-size and application comparison, review 3A vs 4A vs 5A vs 13X Molecular Sieve.
