Zhongsu Hengda is a professional activated carbon filter manufacturer, if the activated carbon is not replaced in time, resulting in poor system water removal and oil removal effect, a large amount of water, oil, impurities into the adsorption tower, will cause irreversible damage to the molecular sieve, carbon molecular sieve if poisoned by oil, will completely lose the analytical ability. The adsorption effect of molecular sieve is poor, resulting in reduced purity of air separation system and reduced gas production. Degreasing agent is the safety guarantee to prevent carbon molecular sieve oil poisoning. Therefore, the activated carbon filter is an indispensable part of the air purification system.
