3.0-5.0mm 4A molecular sieve zeolite in air dryer
A kind of alkali metal alumino-silicate,in the sodium form
of the Type A crystal structure.It could absorb the molecules
which critical diameter is not more than 4 angstroms. The
selective adsorption performance of water is higher than
any other molecules. It is one of the most used
molecular sieve varieties in industry.
Chemical Molecular Formula:
Na2O·Al2O3·2SiO2·4.5H2O. (SiO2 : Al2O3 ≈2).
