Replace carbon molecular sieve

During the use of carbon molecular sieve, improper operation and maintenance can cause poisoning. For example, the pre-air purification is not equipped with treatment equipment or the equipment is running with diseases, causing oil and water impurities to enter the adsorption tower directly with the air and be adsorbed by carbon molecular sieve, causing poisoning, severely impaired resolution, and greatly reduced nitrogen production and purity . In addition, after the carbon molecular sieve reaches a certain service life, its nitrogen purity will be significantly reduced, and the use requirements cannot be guaranteed. In such situations, you have to consider replacing the carbon molecular sieve.
