Is it necessary to change the molecular sieve of PSA nitrogen and oxygen generators?

Incorrectly designed PSA generators from other manufacturers and/or the use of low-quality molecular sieves with insufficient strength do indeed need a regular renewal of their molecular sieve. Fortunately, the PSA generators from NOVAIR don't require such major and very inconvenient overhauls.

As long as the feed air is of sufficient quality, the PSA generators from NOVAIR do not need any renewal of the molecular sieve during their entire lifetime. NOVAIR verifies every new design with extensive CFD calculations and running tests before market introduction to assure low gas speeds through the molecular sieve beds and maximum durability. NOVAIR applies exclusively first-class quality molecular sieves for all its PSA nitrogen and oxygen generators.
