Molecular Sieve 3A

Molecular Sieve 3A

Molecular sieve 3A (so-called zeolites) are drying agents of type A and have 1x n-modules, whereby these zeolites have the highest polarity and preferably exclude water.  These are synthetically produced aluminosilicates. Zeolites of type 3A contain potassium in their crystal lattice (K6Na6[(AlO2)12(SiO2)12]), the resulting pore diameter is approx. 0.3 nm. This constant structure results in a very high inner surface area of up to 1000m²/g. Together with their high electrostatic adsorption forces, these molecular sieves are therefore ideal for air drying.

Molecular sieves achieve a high absorption capacity even at low relative humidity. Thus they are able to dry the supply air very strongly. This makes it useful wherever the degree of drying is a decisive selection criterion. The maximum water absorption in a fully saturated environment is about 21%. There is no colour indicator to indicate the loading condition.
