What is the importance of Vacuum Pressure Swing Adsorption?

Vacuum swing absorption separates certain gases from from a gassy mixture at an atmospheric pressure; the process then swings to a vacuum to regenerate the absorbent material. In vacuum swing absorption, it draws the gas through separation process with a vacuum ensuring each sieve bed is properly rejuvenated in every cycle.

Higher Quality of Sieve Beds with Lower Cost

Other manufacturers use basic pressure system which leads their sieve beds capable of water vapor and residual nitrogen which destroys them over time, causing bed replacements. This advance technology in sieve beds ensure highest oxygen purity, and decreases the need to sieve bed replacement.

Advantages of VSA Technology over PSA Technology

Pressure swing absorption (PSA) is an old technology which leaves sieve beds with nitrogen residual and moisture. While vacuum swing absorb nitrogen efficiently from sieve material while delivering highest purity of oxygen. This vacuum pressure swing adsorption process leaves sieve material as good as it can possibly be at the start of each sieve bed cycle.

• VPSA eliminates any residual nitrogen
• VPSA eliminates any residual water vapor
• No wasted oxygen
• More energy efficient
