1. Check the air treatment process, how is the cooling effect of the dryer, and replace the filter element of the pipe regularly (every six months) to make the air quality better.
2. Replace the activated carbon of the discount ISO standard Chemical Nitrogen Plant and Nitrogen Generator (replace once every 12 months). The activated carbon link is a process of oil removal, which can reduce the oil content in the air and avoid the pollution and poisoning of the carbon molecular sieve of the nitrogen generator.

3. For the detection and calibration of nitrogen analyzer, the general life of nitrogen analyzer is 2-3 years, and it is recommended to replace it when the life expires to avoid misjudgment of the purity of discount ISO standard Chemical Nitrogen Plant and Nitrogen Generator.
4. Check the solenoid valve and pneumatic valve. In order to ensure the normal operation of the equipment, it is recommended that the user keep a backup.
5. The carbon molecular sieve of the nitrogen generator (replaced once every 5-6 years) is analyzed and tested for nitrogen yield to ensure that the nitrogen yield meets the needs of customers. During maintenance, the carbon molecular sieve of discount ISO standard Chemical Nitrogen Plant and Nitrogen Generatorshould be added or replaced according to the customer's usage.
