Attention: CaX can’t be exposed in the open air and should be stored in dry condition with an air-proof package. It can be regenerated after a certain period of adsorption. The appropriate regenerated temperature would be better below 350°C.

Main Application of CaX Molecular Sieve

It is mainly used for oxygen-producing in air separation of pressure swing adsorption.
