Molecular Sieve - Type 4A

Part Number: 4A18-30

  • Molecular Sieve Type 4A is the sodium form of Zeolite.
  • Type 4A is typically used in regenerable drying systems.
  • It removes water vapor or contaminants with a smaller critical diameter than 4 angstroms.
  • With a smaller pore size, Type 4A is less subject to contamination.
  • However, the moisture absorption rate will be less than that of Type 13X.
