PSA pressure swing adsorption nitrogen machine is also called carbon molecular sieve nitrogen machine, as its name shows, its core component is carbon molecular sieve. Carbon zeolite has very strict requirements on the use of environmental conditions. It requires that the compressed air provided by the air compressor must be treated by the cold dryer and multi-stage precision filter (i.e. purification system). In addition to the impurities in water and oil, it ensures that the compressed air entering the nitrogen generator is dry and clean. The blowdown of the cleaning system should be checked regularly, and the filter consumables should be replaced regularly.

In the process of using the nitrogen generator, if the user does not maintain the purification system in time, or if the operation is improper, the purification system will run ill or not run for a long time, resulting in oil and water impurities directly entering into the adsorption tower of the nitrogen generator with the air, blocking the micropores of the carbon molecular sieve, greatly reducing the adsorption capacity of the molecular sieve, and making the purification system in a bad state for a long time. At this time, the user should timely replace the filter element, automatic drain valve and deoiling activated carbon according to the production needs. The most important thing is to replace the carbon molecular sieve in the adsorption tower of the nitrogen generator, so as to restore the normal nitrogen production capacity of the nitrogen generator.
