Lianbang VSA Oxygen Generator saves 50%~70% compared with liquid oxygen, and an extra 30%~40% compared with conventional PSA.The longer the service life and the larger the consumption, the more obvious the advantages are, with a payback period of 1–2 years.
II. Unit Cost Comparison (RMB/Nm³, comprehensive cost)
Lianbang VSA Oxygen Generator: 0.28~0.42
Conventional PSA Oxygen Generator: 0.40~0.65
Purchased Liquid Oxygen: 0.70~1.40
III. Core Advantages of Union VSA (Technical & Cost)
Low-pressure Oil-free VSA Technology
Adsorption pressure < 0.1 MPa, power consumption 30%~40% lower than conventional PSA.
Oil-free air compressor, completely eliminating oil contamination and ensuring cleaner oxygen.
Extremely Low Maintenance Cost
Molecular sieve service life: 8–12 years (only 3–5 years for conventional PSA).
Oil-free design eliminates oil filters and lubricants, reducing annual maintenance cost by over 50%.
More Stable Operation
Oxygen concentration steadily maintained at 93%±3%.
Intelligent frequency conversion, adaptive load regulation, and remote operation & maintenance.
Single-tower structure with small footprint, low investment, and high reliability.
Optimal Comprehensive Cost
50%~70% cheaper than purchased liquid oxygen.
An extra 30%~40% cheaper than conventional PSA.
Payback within 1–2 years under continuous oxygen usage.
