The VSA Adsorber Vessel:
Has a much longer service life whereas PSA vessels commonly require repacking of sieve material every 3-5 years. This, again, presents a much lower operating cost.
Shows no, or significantly less, degradation of performance at high altitudes, unlike PSA technology.
Needs no feed air compressor (> 50% saving vs. conventional systems).
Meets the USP 93% standard and can reach as high as 95%.
Is a turn-key integrated solution, so there is no need to size / source air compressors, dryer systems, and product or feed buffer tanks.
