The advantages of our high quality 4A mole sieve are consistent adsorption speed, and higher contamination resistance, stronger crushing increasing cyclic times that provide an extended product life. 4A Molecular Sieve is primarily for removing moisture from liquefied and gaseous materials.


Regeneration: 4A Molecular Sieve regenerated and reused. To regenerate the sieve you need to remove the adsorbed moisture and other materials. To regenerate 4A Molecular Sieve heat to a temperature of 250ƒ to 450ƒ.

Storage: Keep 4A Molecular Sieve in an air-tight container until ready for use to avoid unintended moisture adsorption.
