PSA Technology: Ambient air is compressed and passed through zeolite sieve beds, which adsorb nitrogen, allowing high-purity oxygen (~90–95%) to pass through in alternating adsorption/desorption cycles.
Purity Control: Adjustments to pressure and cycle times enable fine-tuning of oxygen purity to match specific laboratory needs.
Ultra-High Purity Options: Some advanced models deliver up to 99% purity with stable output and tight concentration controls (±0.2%).
