2. Typical Application:

- Used in air compressors for drying gas;

3. Regeneration:

Chemxin molecular sieve Type 4A can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case of pressure swing processes.
To remove moisture from a 4A molecular sieve, a temperature of 250-280°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process

4. Attention:
To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
