Zeochem 8x12mesh molecular sieve 4A for air dryer

Product Description.

Chemxin Molecular Sieve 4A has an effective pore opening of about 4 angstroms (0.4nm). It will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger. Especially for drying and removing water from natural gas, LPG, air, inert and atmospheric gases etc.
